The attention is on gold for bursting through the $2700 line. And the FRNSI is now over 130. At what point does it become worthwhile to simply wipe your butt with dollar bills rather than lugging them around in your wallet? (Honestly, though, they aren’t absorbent enough…so probably, never.)
As I said the attention is on gold…but silver should not be neglected! It has gone up over two dollars over the past week, and (net) almost all of that was on Friday after four days of almost no net movement. It went up $2.03 on Friday or 6.4 percent. (Versus gold going up 1.05 percent on Friday) And you can see the effect in the Gold:Silver ratio. In terms of silver, gold dropped over three and a half ounces.
Even platinum went up more on a percentage basis Friday than did gold.
*The SteveInCO Federal Reserve Note Suckage Index (FRNSI) is a measure of how much the dollar has inflated. It’s the ratio of the current price of gold, to the number of dollars an ounce of fine gold made up when the dollar was defined as 25.8 grains of 0.900 gold. That worked out to an ounce being $20.67+71/387 of a cent. (Note gold wasn’t worth this much back then, thus much gold was $20.67 71/387ths. It’s a subtle distinction. One ounce of gold wasn’t worth $20.67 back then, it was $20.67.) Once this ratio is computed, 1 is subtracted from it so that the number is zero when the dollar is at its proper value, indicating zero suckage.
Flat Earther Influencers are Mostly Lying Sacks of Shit
The Final Experiment continues to make waves in the Flat Earth Community.
I will link a relevant video below, but I’ll summarize here.
After years of happily saying that a 24 hour sun in Antarctica during southern summer (with it doing a 360 around the viewer over the course of a day) would disprove the Flat Earth viewpoint, but then saying “yeah but you can’t go to Antarctica” or flatly asserting that the sun does set in Antarctica, and furthermore that they’d love to go to Antarctica and see…
They’re for the most part refusing to go take a look. Everything from whining about how they’d have to deal with globe-earth “trolls” on the trip to…well, I don’t know what other rationales they have. There are three, maybe four going. (Four is if you count Candace Owens’ producer.)
Plenty of globe earthers are going, and at least a couple of them have vowed to take down their content and replace it with a video stating that the Earth is flat…if the sun sets during the five days they are at 79+ degrees south latitude.
Meanwhile other flerfers have begged the three that are going, not to go, or have already accused them of being shills. (Interesting. Before they even report back what they have seen, they are already bought off shills. Almost as if the accusers already know they will be reporting back that the Sun did not set!
One would think that if the flerfers are so confident of their position, they would positively relish the prospect of their final victory over the globers, as they point to the twighlight and say “So, Dave, where’s the sun?!?!” as they film McKeegan’s humiliation for their own channels!
That is how they would behave if they were really thinking of themselves as people with some special insight who have had their viewpoint put down and suppressed; they would love to have their day in the court of the brute fact that the sun went down in Antarctica during Antarctic summer.
Instead, with the exception of those who are actually going on the trip, they are acting like knowing con-men whose jig is about to be up.
Those reading this who have accepted the flerfer claims might just want to think about that. That should speak louder to you than all their shitty geometry, bogus astronomy, and physics claims which (let’s face it) should not have fooled any educated adult. The sad, blunt truth of the matter is that you have been suckered.

January 6 Tapes Reminder
After the first release, we were supposed to get more, every week.
As far as I know it hasn’t happened.
Speaker Johnson, please follow through!
A Caution
Just remember…we might replace the RINO candidates. (Or we might not. The record is mixed even though there is more MAGA than there used to be.) But that will make no difference in the long run if the party officials, basically the Rhonna McDaniels (or however that’s spelled–I suspect it’s RINO), don’t get replaced.
State party chairs, vice chairs, secretaries and so on, and the same at county levels, have huge influence on who ultimately gets nominated, and if these party wheelhorses are RINOs, they will work tirelessly to put their own pukey people on the ballot. In fact I’d not be surprised if some of our “MAGA” candidates are in fact, RINO plants, encouraged to run by the RINO party leadership when they realized that Lyn Cheney (and her ilk) were hopelessly compromised as effective candidates. The best way for them to deal with the opposition, of course, is to run it themselves.
Running good candidates is only HALF of the battle!
Biden Gives Us Too Much Credit
…we can move on to the next one.
Apparently Biden (or his puppeteer) has decided we’re to blame for all of the fail in the United States today.
Sorry to disappoint you Joe (or whoever), but you managed to do that all on your own; not only that, you wouldn’t let us NOT give you the chance because you insisted on cheating your way into power.
Yep, you-all are incompetent, and so proud of it you expect our applause for your sincerity. Fuck that!!
It wouldn’t be so bad, but you insist that everyone else have to share in your misery. Nope, can’t have anyone get out from under it. Somehow your grand vision only works if every single other person on earth is forced to go along. So much as ONE PERSON not going along is enough to make it all fail, apparently.
In engineering school we’re taught that a design that has seven to eight billion single points of failure…sucks.
Actually, we weren’t taught that. Because it would never have occurred to the professors to use such a ridiculous example.
Justice Must Be Done.
The prior election must be acknowledged as fraudulent, and steps must be taken to prosecute the fraudsters and restore integrity to the system.
Nothing else matters at this point. Talking about trying again in 2022 or 2024 is hopeless otherwise. Which is not to say one must never talk about this, but rather that one must account for this in ones planning; if fixing the fraud is not part of the plan, you have no plan.

Spot Prices
All prices are Kitco Ask, 3PM MT Friday (at that time the markets close for the weekend). (Note: most media quotes are for the bid…the price paid by the market makers, not the ask, which is what they will sell at. I figure the ask is more relevant to people like us who wish we could afford to buy these things. In the case of gold the difference is usually about a dollar, for the PGMs the spread is much wider.)
Gold see-sawed, getting closer to 2700, almost dipping below 2600 on Wednesday and Thursday but recovered nicely on Friday, even to the point of closing up for the week, barely. Silver, however, has definitely slipped, and you would need almost two more ounces of silver this week to buy an ounce of gold, than last week. Platinum a bit down, palladium might be starting another run.
*The SteveInCO Federal Reserve Note Suckage Index (FRNSI) is a measure of how much the dollar has inflated. It’s the ratio of the current price of gold, to the number of dollars an ounce of fine gold made up when the dollar was defined as 25.8 grains of 0.900 gold.

Once this ratio is computed, 1 is subtracted from it so that the number is zero when the dollar is at its proper value, indicating zero suckage.
Moon Roundup
Before 1610, there was one Moon, and it wasn’t a class of objects. Actually at one time the Moon and Sun (!) were lumped in with Mercury, Venus, Mars, Jupiter and Saturn as planets. They were, after all, all objects that moved with respect to the background stars (that includes the Sun but it takes a little bit of extra work to show this since it’s rather difficult to see the stars and Sun at the same time). And planet derives from a Greek word for wanderer.
Note by the way that Earth was not considered a planet. Planets were things up there in the sky, not down here, and certainly not as “down here” as you can get, the dirt beneath your feet.
This was back in the old “Earth is the center of everything” days, but late in the 1500s some people started suggesting that perhaps it was the Sun at the center. (This was actually a revival of an ancient Greek idea.) Now this is difficult to settle with naked eye observations, but a telescope will show you that not everything goes around the Earth. Venus and Mercury exhibit phases that show they orbit the Sun. And Jupiter, of course, has those Galilean moons.
Galileo actually considered them planets at first, because, after all, they moved against the background stars, just like Jupiter did. He didn’t realize we needed a new category of thing, with the Moon being the first known member. And it took a while; for a couple of centuries the larger moons of the outer planets were called “satellite planets” instead of “moons” or just plain “satellites.”
So if you think Pluto being demoted from planet status was a kerfuffle, imagine what was going on then, when they still couldn’t figure out which buckets even existed that they could put things into (figuratively speaking of course).
Eventually anything that orbited the Sun was a planet, including Earth, and anything that orbited a planet was a satellite or moon, including “the” Moon. We know of no cases of a moon itself having a natural satellite of any significant size.
And yes, “satellite” used to be synonymous with “moon,” but then we started putting things in orbit, and we started talking about natural and artificial satellites. Some people still do so, but most people use “moon” (with a lower case M) for the natural case and just plain “satellite” for the artificial case.
[And yes, we’ve no idea how to classify Stacy Abram’s hindquarters. It’s a moon…sort of…and is of similar size to the major moons, but it’s not a heavenly body by any stretch of the imagination.]
Since those days, of course, we’ve found objects out there of all kinds of different sizes orbiting both planets and the Sun, so we had to sit down and reassess definitions again and Pluto got the boot from the “planet” clique. (And, IMHO, rightly so; the other alternative would have been to promote about half a dozen Kuiper belt objects.) There’s no minimum size, as yet, for moons, so technically any planet with a ring has countless moons: all the constituent rocks that make up the ring.
Anyhow, we’re not even halfway through the moons that are in our solar system. But I thought I’d do a quick roundup, to set up the Big Picture. Let’s start out with a picture from Wikipedia showing planets and large (or famous) moons, all to scale by size. Notably, Mercury and Mars look roughly the size of some of the bigger moons, and Pluto is outclassed by at least seven moons.
Let’s consider them in order of size. If you ignore the planets and Pluto, there seem to be seven “big ones,” and a bunch of medium sized ones.
The big ones are The Moon, Io, Europa, Ganymede, Callisto (all orbiting Jupiter), Titan (Saturn), and Triton (Neptune). They are all 2500 km across or larger. There seems to be a big gap between Triton and any of the moons smaller than it, and when you look at masses, that is confirmed. Triton, the smallest of these seven, is more massive than all of the other moons put together. So you could actually make a list with eight entries, the eighth being “everything else that’s a moon, put together” and that would be the last item on the list.
That makes it seem like a nice, natural dividing line between “large” and “medium.”
The large moons verge on being planet sized, with Ganymede more voluminous than Mercury (though made of much lighter stuff). So much so that at least some astronomers call these seven the “satellite planets.” (I.e., things that would be planets, if only they weren’t orbiting a planet!) [As an aside I suspect we’ll be looking, again, at reclassifying things soon. And I would not be entirely unsympathetic.]
Now just eyeballing that diagram again, there are nine moons in the “medium” bracket (with S for Saturn, U for Uranus, and P for Pluto): Titania (U), Oberon (U), Rhea (S), Iapetus (S), Charon (P), Ariel (U), Umbriel (U), Dione (S), and Tethys (S). And again, it turns out that Tethys, the smallest of the nine, is bigger than all of the remaining “small” moons, put together. So, another natural dividing line, between medium and small. These medium moons are all 1000-2500 kilometers in diameter.
Up to here, moons seem to be named after mythical figures, however for some reason the moons of Uranus got named after Shakespearean characters.
So that’s sixteen medium and large size moons. Everything else is “small.”
But there’s another criterion we could use…and that’s “hydrostatic equilibrium” which when you dumb it down means “is it spherical”?
If you don’t dumb it down, there are nuances. For instance, if a moon is orbiting fairly close to a planet when it’s still largely molten, it’s going to take on an oblate shape, first because it’s rotating once per orbit, and second because the planet’s going to tend to make it egg shaped (tidal forces). If it then solidifies and its orbit gets larger, it’s technically not quite in hydrostatic equilibrium any more; because if it were liquid it would flow into a slightly different shape. Our own moon is actually an example. But in general, for classification purposes, this is a nuance that is ignored; the sucker is round or it isn’t.
[Edited to add:] A moon in hydrostatic equilibrium is considered to be a “major moon,” no matter how small it might be.
[Edited:] All of the large and medium moons are major moons. But as happens, three (maybe four) of the biggest “small” moons, those below 1000km across but greater than 250 km across, are round too and also qualify as major moons. There are two moons in the 500-1000 km range, and seven in the 250-500 km range. I’m going to call the 250-1000 km range the “medium small” range.
[Edited:] In the 500-1000 km range, we have Enceladus (S) barely making it at 504 km, and definitely a major moon. There is also Dysnomia, a satellite of the dwarf planet Eris, which is the “maybe” case. It’s 615 km across, apparently, but it’s very dark and we cannot get a read on its shape though its density appears to be low enough that we don’t expect its gravity will have crushed it into a sphere.
[Edited:] in the 250-500 km range we have Mimas (S), and Miranda (U), 400 and 470 km in diameter respectively, both major moons. And we also have five objects that are not major moons, and they are Hyperion (S), Proteus (N), Nereid (N), Vanth (satellite of dwarf planet Orcus) and Hi’iaka (satellite of dwarf planet Haumea). Proteus is actually bigger than Mimas, so there’s clearly not a hard line, above which a moon will be round (and therefore major). As I alluded to above, a low density can make a moon less massive, which can be enough that it does not “go round.”
[Edited:] So there’s your roundup. Expect to see talk of Large, Medium and Medium-small moons, as well as major moons and minor moons; “major” encompassing large and medium moons as well as three of the scores of small moons.
Saturn
History
Saturn, to the ancients, was a star-like object that took 29.5 years to make one trip around the ecliptic. Dimmer and slower than Jupiter, which was associated with the king of the gods, it got associated with the prior generation.
You see, in Greek and Roman mythology the Olympian gods were the third generation. The first was Uranus (Οὐρανός), the sky, and Gaia, the Earth. He was both her son and her husband. Their children were the titans, twelve of them: Oceanus, Coeus, Crius, Hyperion, Iapetus, Theia, Rhea, Themis, Mnemosyne, Phoebe, Tethys, and Cronus. (You will see some of those names again…in fact if you read the previous section, you already have.) Cronus (or Kronos) was the father of Zeus, Hera, Poseidon, Hades, Hestia, Demeter and Chiron. These are all the Greek names. The one called Kronos was known to the Romans as Saturn.
In 1610 Galileo turned that telescope towards Saturn, and saw…well, a couple of lumps one on each side of Saturn that each looked like it might be a moon a third the size of Saturn. (Let’s face it, it wasn’t a very good telescope, even if it was one of the best in the world at the time.)
A couple of years later, he looked again, and the moons were gone. He predicted that they would be back later, and indeed they showed up. And got bigger to the point where Saturn seemed oval-shaped. Christiaan Huygens finally saw this as rings in 1655, publishing his results in 1659. Huygens spotted one moon, which he named Titan. Shortly thereafter (1675) Giovanni Domenico Cassini discovered a gap in the rings, and also four more moons, Iapetus, Rhea, Tethys and Dione–all named after titans. (Dione is either another daughter of Uranus and Gaia, or the daughter of Oceanus and Tethys, depending on whose rendering of the mythology you’re reading.) In 1789 William Herschel (discoverer of Uranus) discovered two more moons, Mimas and Enceladus–these are two of the three “small” moons in our solar system that are nevertheless big enough to be round, from the previous section. Hyperion was discovered in 1848. It’s comparable to Mimas and Enceladus, but not round…far from it, as we’ll see.
Saturn ends up having seven major moons, one large, the other six medium. Add in Hyperion, and that’s eight. When I was a kid, the count was ten (with most books still saying nine). The missing two were Phoebe (1898) and..well..number ten, first spotted in 1966, was a bit confusing. It was first spotted on December 15, 1966. But then another astronomer spotted it again…but in a different place in the same orbit…on December 18, 1966. Here was a moon that appeared to be jumping around in its orbit, but it was there (well, maybe not) and it was number 10. Finally in 1978, a couple of astronomers realized what was really going on. There were two moons sharing the same orbit, Janus and Epimetheus, a situation which had been assumed to be unstable up until then. So elementary school Steve didn’t realize Saturn’s tenth moon was really the tenth and eleventh moons. Today’s count is (drumroll) one hundred and forty six, with the most recent discovery being in 2020. But I am going to save detailed discussion of the moons until next time.
Pioneer 11 flew by in 1979. Voyager 1 zipped by in 1980, and Voyager 2 followed it in 1981. What a nice little barrage, especially since the cameras on the Voyagers were so much better. After that nothing until 2004, when Cassini went into orbit around Saturn. It not only stayed there for 13 years (until we deliberately deorbited it into Saturn’s atmosphere, since it was about to die anyway), it even put a lander on Titan! The ONLY landing ever made beyond the asteroid belt.
The Planet Proper
Saturn itself orbits at an average distance of 1,434 million kilometers, nearly a billion and a half. That’s 9.58 AUs. It has an axial tilt of about 28 degrees, a bit more than Earth’s 23 degrees, so Saturn definitely has seasons, unlike Jupiter (whose axial tilt is about 2 degrees). This will turn out to be important when we finally quit fiddling around and talk about the rings.
Saturn has a magnetosphere, like Jupiter, Ganymede, and Earth. Unlike Jupiter and Earth, the Saturn “magnet” is aligned with the axis of rotation pretty well. This magnetosphere isn’t as strong as Jupiter’s, but still significant.
Measured across the equator, Saturn is as wide as 9 earths. Measured through the poles, on the other hand, it’s only 8 earths tall. That’s because it is spinning very rapidly, once in about 10 1/2 hours, and it’s fluid clear down to a solid core that’s about 16,000 km across. We were able to learn a LOT about Saturn’s interior just from monitoring its gravity’s effect on both the Cassini probe and the rings.
Saturn has a banded atmosphere much like Jupiter’s though not nearly as colorful. It doesn’t have a long-standing storm like the Great Red Spot, but from time to time white spots will appear. Great white spots tend to appear once every Saturnian year, during its northern hemisphere summer, the last one in 1990. Cassini got to see one form, stretch out along its band, and eventually dissipate, after the head of the thing caught up and passed its tail. And then in 2010, ten years early, we got another white spot.
Voyager 1 spotted something very peculiar around Saturn’s north pole. For some reason we don’t fully understand, the clouds there form a hexagon, which appears to rotate with the planet, in time with Saturn’s radio emissions.
The south pole, by contrast, shows something like a hurricane eyewall. (No word yet on whether this is where all the FEMA hurricane money goes.)
OK, with that out of the way…
The Rings
They have been called “Gravity’s Masterpiece.”
And that is an understatement.
Gravity created them, gravity maintains their structure, and gravity is slowly destroying them.
Galileo noticed change when looking at Saturn, but could not resolve the rings; his telescope was simply too small. That change is caused by Saturn’s seasons. When it’s northern hemisphere summer, the north surface of the rings is tilted toward the Sun, at autumn they are edge on, at northern winter, the south surface is tipped toward the Sun, and finally at northern spring, they are edge on again. And since, comparatively speaking, we’re quite close to the Sun, we see the same thing. Here is a twenty nine year time lapse:
The rings are thin. At the time the earth crosses through the plane of the rings, we can’t see anything, not even a thin line. It has been likened to looking at a sheet of paper edge on, but relatively speaking the sheet of paper is much too thick! The next “disapperance” is next year, right now it looks something like this:
The rings are skinny but definitely there.
The rings are themselves subdivided into seven sections, imaginitively named A, B, C, D, E, F, and G.
What we see through our telescopes are basically A, B, and C. This is typically what you’ll see…only it’s much smaller in the telescope field of view than this:
This picture (from Cassini) shows the rings from well above the plane, with Saturn itself casting a shadow on them.
Going form the outside in, there’s a medium-bright ring (A), a wide gap–the one noted by Cassini, a brighter ring (B), and a much fainter ring (C). There are other, smaller gaps as well. Where do they come from? The Cassini gap happens to be at that spot where, if something were orbiting there, it’d do so in a 2:1 resonance with Mimas. That causes enough instability to force objects into smaller or larger orbits. In other cases, small moons within the rings help clear things out.
That’s just the beginning of the crazy stuff that happens in the rings. Ripples one to two kilometers high raised by embedded moons, spokes on the B ring we can’t figure out (yet)…some scientists are spending their entire careers on this stuff!
To see the D through G rings readily, we must look at Saturn backlit…something we couldn’t do until we sent spacecraft there.
By the way, if you right click and open in new tab, between the two “gray” fuzzy rings (a narrow one and a broad one) at about 4 oclock…that dot there is Earth.
The rings appear to be made of chunks of ice, averaging about a foot across. And they’re pretty bright; they haven’t been covered with dark space dust. That leads most scientists to think that they aren’t that old…150 million years at the most. It’s possible that they weren’t there when the non-avian dinosaurs were killed 66 million years ago.
The most common thought is that a medium-sized moon got too close to Saturn somehow, perhaps thanks to perturbations from the other moons, and tidal forces (yes tidal forces again) did the rest.
Picture this: a spherical body maybe 200 kilometers across in orbit. It will orbit as if the entire mass of the moon were concentrated at the center. But a rock at the far side of the moon is 100 kilometers further away, and one at the near side is 100 kilometers closer. An object 100 km further out, in order to stay in orbit, wants to move slower than this moon is orbiting, yet that rock is being forced to move faster than that, since it’s stuck to the moon. If the moon were to suddenly disappear and leave the rock behind, it would actually go into a new, elliptical orbit, with the closest part where the rock was, sitting on the moon, and the furthest part, oh, some distance away. And so, this is what the rock “wants” to do. It actually feels a slight tug pulling at it, off the surface of the moon. If the moon is close enough to the planet, and its gravity weak enough, the rock will actually feel no net attraction to the moon, and drift off. As will its neighboring rocks. And similar things happen on the side of the moon closest to the planet, they want to go into smaller orbits and feel a net tug toward the planet and off the moon.
That’s how loose rocks might peel off, but moons are generally solid, aren’t they? Sure. But, if you think about that orbit where things on the far side will just barely want to drift away, but put the moon closer, then something deep underground at the far side would (if it weren’t buried) drift away. Now bury it again. Everything above it wants to drift away too. Those miles of stuff are effectively “hanging” wanting to fall off the moon. Enough of that, and even a solid rock will fracture. Rocks don’t do too well under tension, a fact which has had a profound effect on architecture here on Earth.
So, basically, we think a mostly-icy moon got too close and shattered. And the tidal forces have kept it from reforming. However some suggest that instead, two moons collided and this is the debris from the collision.
The rings are dying, though. The ice is slowly sublimating with help from cosmic rays, and that ice ends up in Saturn’s magnetic field and eventually forms auroras in its atmosphere. There are also other forces causing ring material to rain down onto Saturn’s equator (this was discovered by the Cassini spacecraft). The rings have 10-100 million years to live at the rate they are losing mass.
I’ll close this with another picture:
..or two, just to see the aurora…
..or three (you can see the hexagon in this one).
Obviously I could go on. But some of the coolest stuff is on the moons. So…until next time!

MUSIC!
Some interesting period music for a role-playing game related to the Lovecraft story…..
But if that’s not your bag, try this mountain music – supposedly the first ever film of Appalachian music – which was recorded on October 7, 1928 – and posted to the internet on October 7, 2021.
Here for your enjoyment on October 7, 2024.
Good stuff! And speaking of stuff…..

What is it that feeds our battle, yet starves our victory?
January 6 Tapes?
Paging Speaker Johnson…this is your conscience calling you out on broken promises.
For all your high talk about your Christian moral background…you’re looking less and less like you have any kind of moral background.
If You are a Patriot and Don’t Loathe RINOs…
Let’s talk about RINOs, and why they are the lowest form of life in politics.
Many patriots have been involved with politics, often at the grassroots, for decades. We’ve fought, and fought, and fought and won the occasional illusory small victory.
Yet we can’t seem to win the war, even when we have BIG electoral wins.
I am reminded of something. The original Star Trek had an episode titled Day of the Dove. It was one of the better episodes from the third season, but any fan of the original series will tell you that’s a very low bar. Still, it seems to get some respect; at a time when there were about 700 episodes of Star Trek in its various incarnations out there, it was voted 99th best out of the top 100.
In sum, the plot is that an alien entity has arranged for 39 Enterprise crew, and 39 Klingons, to fight each other endlessly with swords and other muscle-powered weapons. The entity lives off of hostile emotions, you see and it wants a captive food source. (The other 400 or so Enterprise crew are trapped below decks and unable to help.) Each side has its emotions played and amplified by the alien entity; one Enterprise junior officer has false memories implanted of a brother who was killed by Klingons. The brother didn’t even exist.
Even people killed in a sword fight miraculously heal so they can go do it again.
The second best line of the episode is when Kang, the Klingon captain, notes that though they have won quite a number of small victories including capturing Engineering, can’t seem to actually finally defeat the Enterprise crew. He growls, “What power is it that feeds our battle yet starves our victory?*”
Indeed. He may have been the bad guy, but his situation should sound familiar.
We are a majority in this country. We have a powerful political party in our corner. There is endless wrangling.
And yet,
What power is it that feeds our battle yet starves our victory?
In our case, that power is the RINOs in our midst. They specialize in caving when on the verge of victory. Think of Obamacare’s repeal failing…by one Republican vote. Think of the way we can never seem to get spending under control (and now our entire tax revenue goes to pay interest on the debt; anything the government actually does now is with borrowed money).
We have a party…that refuses to do what we want it to do, and that refusal is institutionalized. If you’ve been involved with GOP politics, but haven’t seen this, it’s because you refuse to see it. Or because you are part of the problem yourself. (If so, kindly gargle some red fuming nitric acid to clear the taste of shit out of your mouth, and let those not part of the problem alone so they can read this.)
We fight to elect people, who then take a dive when in office. But it’s not just the politicians in office, it’s the people behind the scenes, the leaders of the national, state and county branches of the party. Their job is to ensure that real patriots never get onto the general election ballot. They’re allowed a few failures…who can then become token conservatives who will somehow never manage to win (Jordan), or can be compromised outright (Lauren Boebert?).
That way it doesn’t actually matter who has a congressional majority. I remember my excitement when the GOP took the Senate in 1980. But all that did was empower a bunch of “moderate” puddles of dog vomit like…well for whatever reason forty years later the most memorable name is Pete Domenici. And a couple of dozen other “moderates” who simply had no interest in doing what grassroots people in their party–those same grassroots people who had worked so hard to elect them–wanted them to do.
Oh, they’ll put up a semblance of a fight…but never win. And they love it when we fight the Dems instead of fighting them. Just like that alien entity, whose motto surely was “Let’s you and him fight. It’ll be delicious!”
If you think about it, your entire political involvement has come to nothing because of these walking malignant tumors.
That should make you good and mad.
The twenty five who blocked Jordan, and the hundred people who took that opportunity to stab Jordan in the back in the secret ballot should make you good and mad.
I’ll close this with another example of RINO backstabbing, an infuriating one close to home.
In my county, the GOP chair is not a RINO. She got elected when the grassroots had had enough of the RINOs. Unfortunately the state organization is full of RINOs, and the ousted county RINOs have been trying to form a new “Republican Party” and get the state GOP to recognize them as the affiliate. I’m honestly amazed it hasn’t happened yet.
In other words those shitstains won’t just leave when they get booted out; they’ll try to destroy what they left behind. It’s an indication that they know we know how important that behind-the-scenes party power is.
So they must be destroyed. That’s the only way they’ll ever stop.
We cannot win until the leeches “on our side” get destroyed.
What power is it that feeds our battle yet starves our victory?*
We know it. What is going to be done about it?
*NOTE: The original line was actually “What power is it that supports our battle yet starves our victory.” I had mis-remembered it as feeds. When I checked it, it sure enough was “supports” and that’s what I originally quoted. On further reflection, though, I realized my memory was actually an improvement over the reality, because feeds is a perfect contrast with starves. I changed it partway through the day this originally posted, but now (since this is a re-run) it gets rendered this way from the start.
If one must do things wrong, one should do them wrong…right.
RINOs an Endangered Species? If Only!
According to Wikipoo, et. al., the Northern White Rhinoceros (Ceratotherium simum cottoni) is a critically endangered species. Apparently two females live on a wildlife preserve in Sudan, and no males are known to be alive. So basically, this species is dead as soon as the females die of old age. Presently they are watched over by armed guards 24/7.
Biologists have been trying to cross them with the other subspecies, Southern White Rhinoceroses (Rhinoceri?) without success; and some genetic analyses suggest that perhaps they aren’t two subspecies at all, but two distinct species, which would make the whole project a lot more difficult.
I should hope if the American RINO (Parasitus rectum pseudoconservativum) is ever this endangered, there will be heroic efforts not to save the species, but rather to push the remainder off a cliff. Onto punji sticks. With feces smeared on them. Failing that a good bath in red fuming nitric acid will do.
But I’m not done ranting about RINOs.
The RINOs (if they are capable of any introspection whatsoever) probably wonder why they constantly have to deal with “populist” eruptions like the Trump-led MAGA movement. That would be because the so-called populists stand for absolutely nothing except for going along to get along. That allows the Left to drive the culture and politics.
Given the results of our most recent elections, the Left will now push harder, and the RINOs will now turn even squishier than they were before.
I well remember 1989-1990 in my state when the RINO establishment started preaching the message that a conservative simply couldn’t win in Colorado. Never mind the fact that Reagan had won the state TWICE (in 1984 bringing in a veto-proof state house and senate with him) and GHWB had won after (falsely!) assuring everyone that a vote for him was a vote for Reagan’s third term.
This is how the RINOs function. They push, push, push the line that only a “moderate” can get elected. Stomp them when they pull that shit. Tell everyone in ear shot that that’s exactly what the Left wants you to think, and oh-by-the-way-Mister-RINO if you’re in this party selling the same message as the Left…well, whythefuckexactly are you in this party, you lying piece of rancid weasel shit?
Justice
It says “Justice” on the picture.
And I’m sure someone will post the standard joke about what the fish thinks about the situation.
But what is it?
Here’s a take, from a different context: It’s about how you do justice, not the justice that must be done to our massively corrupt government and media. You must properly identify the nature of a person, before you can do him justice.
Ayn Rand, On Justice (speaking through her character John Galt, in Atlas Shrugged):
Justice is the recognition of the fact that you cannot fake the character of men as you cannot fake the character of nature, that you must judge all men as conscientiously as you judge inanimate objects, with the same respect for truth, with the same incorruptible vision, by as pure and as rational a process of identification—that every man must be judged for what he is and treated accordingly, that just as you do not pay a higher price for a rusty chunk of scrap than for a piece of shining metal, so you do not value a rotter above a hero—that your moral appraisal is the coin paying men for their virtues or vices, and this payment demands of you as scrupulous an honor as you bring to financial transactions—that to withhold your contempt from men’s vices is an act of moral counterfeiting, and to withhold your admiration from their virtues is an act of moral embezzlement—that to place any other concern higher than justice is to devaluate your moral currency and defraud the good in favor of the evil, since only the good can lose by a default of justice and only the evil can profit—and that the bottom of the pit at the end of that road, the act of moral bankruptcy, is to punish men for their virtues and reward them for their vices, that that is the collapse to full depravity, the Black Mass of the worship of death, the dedication of your consciousness to the destruction of existence.
Ayn Rand identified seven virtues, chief among them rationality. The other six, including justice, she considered subsidiary because they are essentially different aspects and applications of rationality.
I’m sure enough of this that I put my money where my mouth is.
The prior election must be acknowledged as fraudulent, and steps must be taken to prosecute the fraudsters and restore integrity to the system. (This doesn’t necessarily include deposing Joe and Hoe and putting Trump where he belongs, but it would certainly be a lot easier to fix our broken electoral system with the right people in charge.)
Nothing else matters at this point. Talking about trying again in 2024 or 2026 is pointless otherwise. Which is not to say one must never talk about this, but rather that one must account for this in ones planning; if fixing the fraud in the system is not part of the plan, you have no plan.
This will necessarily be piecemeal, state by state, which is why I am encouraged by those states working to change their laws to alleviate the fraud both via computer and via bogus voters. If enough states do that we might end up with a working majority in Congress and that would be something Trump never really had.

Interestingly silver did fairly well this week (it’s now worth more than 1/83rd of an ounce of gold now), gold, on the other hand, is slightly down, Platinum seems to be the biggest loser this week.
*The SteveInCO Federal Reserve Note Suckage Index (FRNSI) is a measure of how much the dollar has inflated. It’s the ratio of the current price of gold, to the number of dollars an ounce of fine gold made up when the dollar was defined as 25.8 grains of 0.900 gold. That worked out to an ounce being $20.67+71/387 of a cent. (Note gold wasn’t worth this much back then, thus much gold was $20.67 71/387ths. It’s a subtle distinction. One ounce of gold wasn’t worth $20.67 back then, it was $20.67.) Once this ratio is computed, 1 is subtracted from it so that the number is zero when the dollar is at its proper value, indicating zero suckage.
How QR Codes Work
A Common Phenomenon
Regardless of what you think about Flat Earth, this video should serve to illustrate a common mistake that I see many “conspiracy theorists” (the stupid kind I mean) make.
Basically the man in question went to the NBC website and saw a distorted version of this very famous, even iconic photograph, which even has a nickname, the Blue Marble, because when it came out in the early 1970s there was all sorts of buzz about how the Earth was a Big Blue Marble (great way to propagandize the kiddies!):
…and then proceeded on the implicit assumption that the distortion was the original. In the distortion, it appears as though the Red Sea (between Egypt and Saudi Arabia) was cut in half. Since it isn’t in fact cut in half, he assumed this was proof that the Blue Marble photo was originally faked. (BTW this photo should be 3000 pixels across if you want to fullscreen it, etc. As a bonus, it shows Antarctica so that’s doubly annoying to flerfers.)
When he did a bit more searching for the image, including on the NASA website, he started finding the actual original (with properly rendered Red Sea) a lot and assumed that NASA or someone had been going all over the web and cleaning up their mistakes…except, apparently, on NBC’s website, which somehow got overlooked.
I can assure anyone here who might actually think this guy is onto something and the distortion is the real version, that I have print books from the 1970s that show the photo with an uninterrupted Red Sea. Unless you want to claim that NASA broke into my house and swapped out the books with equally-worn copies…
This is a classic example of a phenomenon I see sometimes…a person with a nutty conspiracy theory latches onto the first thing they see, and if it happens to contain a bona fide error in it, there’s no convincing them of it; they will spin a huge unlikely story as to how “their” version of whatever it was is the correct one, and that the correct one is actually the fake used for a cover up.
Another example of this was a report early on in the Sandy Hook saga that described the wrong gun as being in someone’s trunk. Attempts to correct it were treated as part of the cover up. Interesting that people who would normally have no trouble believing a YSM jurinalist would fuck up especially when the subject was eeevil gunz, believed that this particular jurinalist at this particular time was infallible–because they wanted to believe Sandy Hook was a fake.
What’s going on in both cases is seizing on (apparent) evidence that one’s pet mistaken theory is true, and resisting any attempt to show that this particular piece of evidence, at least, is flawed–sometimes to the point of having to posit another incredibly elaborate or expensive effort to hide the “real” evidence. A mistake, a distorted jpeg, or something similar. This is actually a form of confirmation bias.
The Moons of Jupiter
Jupiter has 95 (yes, ninety five) known moons (as of 5 February 2024). When I was a kid, the number was twelve, though older books in the elementary school library would show eleven. Then a 13th moon was discovered when I was ten (1974), another one the following year, and then the Voyager spacecraft found three more…and at that point they decided they really ought to get on with naming them. The first five or so had been named for quite some time, it was the remaining sixseveneightnine (dammit) twelve that hadn’t been officially named though there were several suggested lists. (The next discovery wasn’t until 2000; the remaining 78 moons have all been discovered since then). Today, of course the list has outstripped our ability to think of names and the newly discovered ones are given temporary designators like S2022 J 3, for 3rd Satellite of Jupiter discovered in 2022.
Astronomers love to categorize things. And the moons of Jupiter are no exception. There are nine categories and I will cover them almost in order of distance from the planet.
The Main Moons, or Galilean Moons, are Io, Europa, Ganymede, and Callisto, in order outwards from Jupiter. These are BIG. They are bigger than any dwarf planet (and that includes Pluto). Ganymede is bigger than Mercury and Callisto almost beats Mercury as well. All are spherical, as one would expect from bodies that size. The innermost orbits at 422 thousand kilometers (from the center of gravity of the Jovian system, essentially the same as the center of Jupiter), the outermost at 1,883 thousand kilometers. (For comparison, our Moon orbits at 384 thousand kilometers, so these are all further from Jupiter than our Moon is from us.) These were all discovered about 30 milliseconds after Galileo first pointed a telescope at Jupiter in 1610; you can see them in binoculars. They all orbit in nearly circular orbits (the key word, as we will see, is nearly), in planes within half a degree of Jupiter’s equatorial plane, all in a prograde (forward) direction. Forward, here, means counterclockwise as seen from way out in space, over the Sun’s north pole. Almost every large body in the solar system both orbits (either the sun or a planet) and rotates prograde, including Earth and the Moon.
Another group of four moons are called the “Inner Moons,” they all orbit within the orbit of Io. The first of these is the first moon to be discovered since Galileo, in 1892, and got named Amalthea. Amalthea is an irregular lump about 167 km across. Much smaller than the Galilean satellites and too small to force itself into a spherical shape. The other three are the ones discovered by the Voyager spacecraft in 1979/80, and are considerably smaller still. There’s also a lot of debris in that region, forming Jupiter’s rather tenuous ring system. Again, these are in nice and tidy, nearly circular orbits in Jupiter’s equatorial plane, all prograde.
Together these groups are called the “Regular Satellites” of Jupiter, which means the other 87 moons are all “Irregular Satellites.”
The Irregular Satellites all orbit much further away from Jupiter than Callisto (the outermost regular satellite). These in turn are divided into prograde and retrograde (orbiting backwards) groupings, each of those is divided again into actual groups. There is a naming convention, too. A prograde irregular moon will have a name ending in -a. A retrograde irregular moon will have a name ending in -e. Not withstanding this, a moon with a very high inclination will have a name ending in -o, whether or not it’s retrograde or prograde.
Prograde groups include Themisto…which is a group all unto itself. It’s the innermost of the irregular satellites averaging roughly 7.4 million km from Jupiter. It’s in a very elliptical orbit (0.340 on a scale from 0 [circular] to 0.9999… [skinniest ellipse possible]) at a 43.8 degree inclination, not at all tidy. It takes about 130 days to complete one orbit about Jupiter.
The next group is the Himalia group of nine satellites, named after its largest member, which is roughly 140 km across. They all orbit at about a 28 degree inclination with eccentricities ranging from 0.1 to 0.24. Average distance from Jupiter is 11.1 to 12.3 million kilometers, most of them being 11.4 or 11.7. They take about 260 days to orbit Jupiter. Four of these are big enough to be in the “classic” 14 satellites from before Voyager I and 2. These orbits are all quite similar to each other, hence the grouping together. It’s likely these were all part of a larger body at some time in the past.
The Carpo group, 2 satellites, are 16-17 million kilometers from Jupiter and are inclined at 50 degrees, which subjects them to all sorts of wacky perturbations resulting in cyclical changes to their orbits. Their eccentricities are very different from each other.
And then there is Valetudo, a group unto itself, in an eccentric orbit 17 million kilometers from Jupiter, at a lesser inclination than the Carpo group. It actually crosses the orbits of other groups’ satellites.
Now we get to the retrograde groups, three of them. The Ananke group ranges from 19-22 million kilometers from Jupiter and there are 26 of them. A quick eyeball scan of the list on Wikipedia shows inclinations from 145-152 degrees. (A retrograde orbit can also be thought of as going forward, but with an inclination of over 90 degrees so it’s “flipped over”, and this is how they get listed in tables of orbital elements.) Inclinations are mostly 0.20 to 0.23. It’s thought that these have a common origin, their orbits are just too similar for it to be pure chance.
The other two groups are the Carme and Pasiphae groups, with 30 and 18 members respectively. They overlap in terms of average distance from Jupiter, 22.6-24.2 million kilometers from Jupiter, taking as long as two Earth years to make one orbit. The Carme group inclinations are all about 164 degrees (i.e., 74 degrees but going around backwards), the Pasiphae groups are in a broader range centering on 150 degrees or so. In each case the satellites in each group are thought to have a common origin.
“Common origin” or “were once part of a larger body”, by the way, imply that there are more undiscovered fragments of what they used to be. The smallest size I see in the table is ~1 km, but conceivably there could be a lot of smaller and smaller pieces. 100 meters, boulder size, gravel size, sand grain size…at what point do you stop and say “this isn’t a moon any more”? It’s a serious question from me, actually. I’m sure that “real” astronomers have given it thought, but I don’t know if they ever actually came to a decision. It did, after all, take hundreds of years for them to define “planet” and they were only forced to do that when they found too many edge cases…a story for another time. (And here, they haven’t started finding really small items in Jovian orbit…when that happens they’ll have to decide where to draw the line if they haven’t already.)
So…broad patterns? Note that the retrograde satellites (by count, most of the satellites are in these groups) are all further out than any of the prograde ones. The retrogrades are almost always 2 km or less in size, though each group has one fairly large body in it, 35-60 km across, probably the “main” piece of whatever broke up to form the group. It’s thought that the retrograde groups resulted from captured asteroids.
There also seems to be a hard 24 million kilometer limit. I haven’t cranked numbers but I suspect that beyond this range the Sun’s gravitational pull is stronger than Jupiter’s, so it would tend to grab any satellite of Jupiter’s that happened to be in a larger orbit than this.
In any case, the retrogrades are basically debris, and even the irregular progrades are basically junk too. Except for the fact that they make good studies in orbital mechanics, they’re pretty uninteresting.
The interesting moons are the Galilean moons. And with that I submit my entry to the understatement of the year contest.
The Galilean Moons (because who gives a rat’s ass about the other 91 moons?)
The Galilean moons are, in order outward from Jupiter, Io, Europa, Ganymede and Callisto. Jupiter plus these moons actually looks like a miniature solar system, and you’ll hear the term “Jovian system” used to refer to the ensemble as a whole.
Although Galileo is given credit for discovering these moons, they were also seen by Simon Marius, and he gave them their names; Galileo simply called them Jupiter I, Jupiter II, and so on, a system which continues to this day; now Roman numerals are given out to newly discovered moons in the order they are named.
“Io” is pronounced “EYO-oh.” Don’t be like the clueless science jurinalist who pronounced it “ten” when the Voyagers flew by. (In his defense, that was the era when Bo Derek was the Queen Hot Woman of All Time thanks to the movie 10…for a whole two months.)
Here is a picture showing relative sizes, Jupiter and the four Galileans, in order top to bottom. This is actually a composite, just to show relative sizes; you’d never see this exact thing all at once.
And another, a real-time shot of Jupiter and all four Galileans. Since some are closer than others, it’s not quite to scale; it is however a “real” snapshot of all five bodies at the same time. If you were to somehow have been able to stand there, this is what you’d have seen. Two of the moons are probably invisible; if so, right click and select “open image in new tab” and even there they will be just single-pixel dots, and one is barely more than a dot)
And now for some raw numbers, with our own Moon tossed in for comparison:

Note that Ganymede is by far the largest; it’s even larger than the planet Mercury.
But also note something else: In the time it takes Ganymede to orbit Jupiter once, Europa will orbit exactly twice, and Io will orbit exactly four times. This is known as an orbital resonance. However, they won’t line up all at once. Io will lap Europa on one side of Jupiter, and then on the other side of Jupiter, Europa will lap Ganymede. See the animation below, where the inner moons will lap “above” Jupiter, and Europa and Ganumede will lap “below” Jupiter.
That’s a simulation, what’s below is based on actual data (notice the time stamp):
This turns out to be important.
Another thing to note is the average densities. Io and Europa (and our Moon) all have densities a bit above 3.0 that of water. We know our own moon is a big ball of rock with very little nickel-iron in its core. And your average generic rock has about that density (though there are plenty of kinds of minerals that come in far higher, such as for instance native gold, a/k/a gold nuggets). So this isn’t unreasonable for moons of Jupiter. However Ganymede and Callisto are considerably less dense, an indication that they are largely ice.
Jupiter I: Io
Io has a very unusual appearance, it almost looks like a pizza. As it happens, it is the most volcanically active body in the solar system. If you don’t like its looks, come back an a few centuries; the entire surface will have been replaced. That’s how volcanic it is. it even has mountains taller than Everest!
This is a pair of pictures of Tvashtar Paterae, taken in November 1999 and February 2000, and yes, that’s lava in the right hand frame.
Volcanism requires heat. And if you’ll recall, Mars…a considerably larger body…does not have volcanism any more (in spite of the largest known volcano being there). Mars has cooled off too much. Why hasn’t Io cooled off?
The answer is (wait for it) tidal forces. (I warned you before I started the tour of the solar system that tidal forces would show up when you least expect them…I did warn you.) Io is in a slightly elliptical orbit (very slightly but still, not quite perfectly circular) and that means it slows down and speeds up in different parts of its orbit, while its rotation (tidally locked to Jupiter) is at a constant rate. This causes Io to stretch and compress, which generates the heat, which causes the insane amounts of volcanism. The surface coloration is largely sulfur. Io’s eruptions have been captured on camera by Voyager, the Galileo orbiter, and Juno.
Some of the stuff that gets erupted ends up in orbit around Io, as very small particles perhaps even single atoms, and some of that gets heated and escapes into orbit around Jupiter. At some point much of this stuff gets ionized. As a result there’s a “neutral cloud” near Io, and a donut or torus of ionized matter roughly where Io orbits. Since this stuff is charged and moving, it actually contributes to Jupiter’s magnetic field…perhaps as much as 50 percent of the total.
This picture not only shows the torus of ionized Io-stuff in red and the neutral cloud in yellow, it shows a third feature in green, the flux tube, which connects Io to Jupiter’s polar regions and can cause aurora-like displays in Jupiter’s atmosphere. But Io itself can have interesting displays, visible when it is in Jupiter’s shadow:
(From the caption on Wikipoo: Auroral glows in Io’s upper atmosphere. Different colors represent emission from different components of the atmosphere (green comes from emitting sodium, red from emitting oxygen, and blue from emitting volcanic gases like sulfur dioxide). Image taken while Io was in eclipse.)
Another source of tidal forces is the pull of Europa and Callisto, with the resonances enhancing the effect.
This was a total surprise when it was discovered back around 1980. And since then it has become clear to planetary scientists that in many cases the moons of the outer planets can be more interesting than the planets themselves.
Jupiter II: Europa
Most especially the second Galilean moon, Europa. What we see when we look at Europa is a solid sheet of ice; it’s the smoothest body in the solar system, and appears to have a 100km thick layer of water above the typical rocky interior. What makes it interesting, though, is that that 100km layer is almost certainly not frozen solid. It’s probably tens of kilometers of ice, sure, but above a world-wide ocean of liquid water, a lot of it, probably more than we have on Earth. (So aliens coming here to steal our water [which is ridiculous because water is almost certainly the most common compound in the universe] would be better off going to Europa.)
(From Wikipoo caption: Closeup views of Europa obtained on 26 September 1998; images clockwise from upper left show locations from north to south as indicated at lower left.)
That water is likely heated by volcanic activity too, for the same reason as Io…but less so. Tidal forces are much lower here. However, the forces will often crack the ice layer, and liquid water will rise under the pressure, with the breaks freezing over, which results in the darker lines. These areas might offer better access to the water, which we want because…
Water is the one thing all life (that we know of!) needs. Not oxygen, but water! This makes Europa a prime candidate for extraterrestrial life, especially since we know that on Earth, “smokers” on the ocean floor host entire ecosystems, and such “smokers” are almost certainly present on Io.
Neil deGrasse Tyson, staying in his lane academically, has said he wants to go ice fishing on Io. He’s not alone in this.
On the 10th of this month, we will launch the Europa Clipper, a spacecraft that will orbit Jupiter, but do so in a way that maximizes the time it will spend on Europa flybys. It’s the largest interplanetary spacecraft developed by NASA. Since it is so big, the booster needs help; it will do gravity boosts off Earth and Mars before arriving at Jupiter in April 2030. This is just a preliminary for a Europa Lander, still on the drawing board.
We’re going after Europa with gusto!
Jupiter III: Ganymede
Ganymede is also covered in ice, with a likely liquid ocean 200km down. It’s colder and harder to get to, so it’s not as tantalizing as Europa. It’s not completely geologically dead: it apparently has at least some liquid iron in its core since it actually possesses a magnetosphere (so far the only moon known to do so). It’s the largest moon in the solar system. As I’ve noted before, it’s actually larger than the planet Mercury, but only 45 percent as massive since so much of it is ice, and because Mercury has a very large iron core for its size. The surface area is in fact over half as much as all of the land on Earth. Unfortunately, it’s mostly ice–and not just a covering, but a full crustal layer of it–and blasted by radiation from Jupiter’s magnetosphere, so it turns out not to be a good place for a realtor to hang a “for sale” sign.
This is Tros crater. In mythology, Tros was Ganymede’s father, and Ganymede himself was Jupiter’s cupbearer (and likely homosexual lover)
Ganymede also has the distinction of being the largest body in the solar system with no significant atmosphere.
Jupiter IV: Callisto
Callisto is a bit smaller than Ganymede, and is the third largest moon in the solar system. (#2 is Titan, a moon of Saturn. And our moon is at #5, just ahead of Europa.) Callisto is remarkable for being very heavily cratered, an indication that its surface has not eroded much or been “worked over” by processes on Callisto itself. It’s far enough out from Jupiter to have very little effect from tidal forces, and it’s not in any sort of resonance with the other moons. Callisto, in fact, has an impact basin named Valhalla, which is 3800 kilometers across!
Callisto may, in fact, be an even mixture of rock and ice, not even having differentiated much with the heavy stuff going down to the core when it formed.
Of the four, Callisto is of least interest for finding life, but it is of great interest for perhaps preserving it. It’s far enough away from Jupiter’s magnetic field and radiation belts that it could perhaps be useful for a manned base from which we could explore the rest of the Jovian system.
So that is a summary of the Moons of Jupiter, all of which rank among the most interesting bodies in our solar system. Were they not in orbit about Jupiter, they’d all be planets in their own right.
As a bonus I will conclude with this diagram, which shows many of the moons in the Solar System, with Pluto and Earth thrown in for good measure. Any moon large enough to force itself into a spherical shape is shown here.

I obtained the word “montero” randomly, but when I searched on it for music, it came up with a song and album that was foisted on us by the satanists and communists in Hollywood and Nashville, via that horrifyingly creepy “Lil Nas X”. You may remember him.
I am not going to reproduce the blatantly homophilic, pedophilic, and anti-Christian content which is revealed in the Wiki article, but one quickly realizes that this “talent” was created to be pro-pedo (“Lil”), Madonna-style mocking and appropriating (“Nas” and “X”), and generally satanic, in a Travis Scott way.
The fact that “they” would send this guy into country music and even the Super Bowl shows the utter DISDAIN that Hollyweird and their satanic outpost in Nashville actually have for the “country” crowd.
Rather than listen to the toxic music, check out this very positive review of the album. Listen to all the details. The enemy’s moves just spill out one after the other!
The opening face-palm image on the video is rather precious in retrospect.

January 6 Tapes?
Where are the tapes? Anyone, Anyone? Bueller? Johnson??
Paging Speaker Johnson…this is your conscience calling you out on broken promises.
News Flash
Today, it is still the case that Joe Biden didn’t Win.
I realize that to some readers, this might be a shock; surely at some point things must change and Biden will have actually won.
But the past cannot actually be changed.
It will always and forever be the case that Joe Biden didn’t win.
And if you, Leftist Lurker, want to dismiss it as dead white cis-male logic…well, you can call it what you want, but then please just go fuck off. No one here buys that bullshit–logic is logic and facts are facts regardless of skin color–and if you gave it a moment’s rational thought, you wouldn’t either. Of course your worthless education never included being able to actually reason–or detect problems with false reasoning–so I don’t imagine you’ll actually wake up as opposed to being woke.
As Ayn Rand would sometimes point out: Yes, you are free to evade reality. What you cannot do is evade the consequences of evading reality. Or to put it concretely: You can ignore the Mack truck bearing down on you as you play in the middle of the street, you won’t be able to ignore the consequences of ignoring the Mack truck.
And Ayn Rand also pointed out that existence (i.e., the sum total of everything that exists) precedes consciousness–our consciousnesses are a part of existence, not outside of it–therefore reality cannot be a “social construct” as so many of you fucked-up-in-the-head people seem to think.
So much for Leftist douchebag lurkers. For the rest of you, the regular readers and those lurkers who understand such things: I continue to carry the banner once also carried by Wheatie. His Fraudulency didn’t win.
Let’s Go, Brandon!!
His Fraudulency
Joe Biteme, properly styled His Fraudulency, continues to infest the White House, we haven’t heard much from the person who should have been declared the victor, and hopium is still being dispensed even as our military appears to have joined the political establishment in knuckling under to the fraud.
One can hope that all is not as it seems.
I’d love to feast on that crow.
(I’d like to add, I find it entirely plausible, even likely, that His Fraudulency is also His Figureheadedness. (Apparently that wasn’t a word; it got a red underline. Well it is now.) Where I differ with the hopium addicts is on the subject of who is really in charge. It ain’t anyone we like.)
Justice Must Be Done.
The prior election must be acknowledged as fraudulent, and steps must be taken to prosecute the fraudsters and restore integrity to the system.
Nothing else matters at this point. Talking about trying again in 2024 is hopeless otherwise. Which is not to say one must never talk about this, but rather that one must account for this in ones planning; if fixing the fraud is not part of the plan, you have no plan.

The Asteroids
In 1772 Johan Elert Bode citing Johan Daniel Titius, formulated the Titius-Bode law, more commonly just “Bode’s Law.” They had noted a rather interesting pattern in the distances of the planets from the Sun, when expressed in AUs. Let’s show the ones known as of 1772, plus the Hugh Janus, discovered in 1781.
Mercury
0.387
Venus
0.723
Earth
1.000
Mars
1.523
Jupiter
5.203
Saturn
9.537
Uranus
19.191
Distances from the Sun to all planets known as of 1800, in Astronomical Units.
The thing is, there’s a pattern here…sort of, and that’s Bode’s Law. It’s a mathematical progression. Start with 4. Then 4+3. Then 4+(3×2). Then 4+(3×4).
Or slightly more clearly: 4, 4+3×20, 4+3×21, 4+3×22, 4+3×23, etc. It’s not quite a perfect series because there’s no way to get 4+0 by adding 3×2some-power to it. Anyhow, let’s divide these numbers by 10 and compare to the planet distances:
Mercury
0.387
0.4
Venus
0.723
0.7
Earth
1.000
1.0
Mars
1.523
1.6
???
2.8
Jupiter
5.203
5.2
Saturn
9.537
10.0
Uranus
19.191
19.6
Distances from the Sun to all planets known as of 1800, in Astronomical Units, with Bode’s Law.
It’s a decent (but not great) fit! And when Uranus was discovered in 1781, it almost fit too, albeit missing by a bit over 0.4 AUs. This made it seem more and more like this law might actually mean something. But if so, the glaring WTF in the whole thing is the fact that we seem to be missing a planet at 2.8 AU.
(I’ll pause here to point out that we no longer think of this as a law. It was valid to think of it as one back then, since a “law” just says “things behave this way, for whatever reason.” Neptune is in completely the wrong place, plus extrasolar planets don’t even remotely follow anything like this even if you scale for the fact that most of them orbit red dwarfs and do so much closer to them.)
But back then, it certainly looked as if we might have a planet to find, especially after Hugh Janus’s discovery made the notion of undiscovered planets thinkable, and Hugh Janus was even at close to the right distance!
On the other hand, Immanuel Kant, when he wasn’t doing things that would later piss off Ayn Rand, did do some theoretical astronomy and he wondered if perhaps Jupiter’s gravity had created the gap.
Many people (not nearly enough in Ayn Rand’s opinion) paid no attention to Kant, and tried looking.
We didn’t have to wait all that long. Just for a new century.
On January 1, 1801, technically the first day of the 19th century, Giuseppe Piazzi, working at the Palermo Astronomical Observatory in Sicily…[OK, I can’t even see the word “Palermo” without hearing in my head a British voice telling Field Marshal Montgomery that Patton had taken Palermo…to which the response was “Damn!” Thanks to the movie Patton.] Anyhow, Piazzi first sighted an object, and repeated his observations from night to night…and it was moving against the background stars! He was able to tell it was not a comet.
We had our planet, named Ceres after the Roman god of agriculture, in keeping with the classical mythological theme; all other planets were named after Roman gods and goddesses, except for Uranus, which was named after the Greek sky god, father of Saturn/Kronos, who was in turn the father of Jupiter/Zeus. (The Roman name would have been “Caelus.”)
It was even at the right distance, 2.77 AU on average, varying between 2.55 and 2.98 AUs.
[Speaking of Uranus…the metal uranium (discovered 1789, isolated in pure form 1841) was named after Uranus, the metal cerium (discovered 1803, isolated in pure form 1838) was named after Ceres. Unlike uranium, you probably have some cerium in your house; typically the enamel on the inside of a self-cleaning oven is largely cerium oxide, which helps cause hydrocarbons to burn during the cleaning.]
It wasn’t much of a planet; it appeared as no more than a point of light in telescopes, whereas other planets showed a disc. And then, before we could really confirm it, it ended up in conjunction with the Sun…in other words, it was directly behind the Sun as seen from Earth. Carl Friedrich Gauss calculated where it would show up after the conjunction, and on 31 December of that year, it was picked up and tracked.
But then it got crazy. Three more asteroids were discovered over the next three years, Pallas (->palladium), Juno, and Vesta. And then nothing, for decades, when Astraea was found in 1845. Then they started coming in, 15 asteroids had been found by 1851, and 100 by 1868.
All were tiny. Ceres had a respectable size, but even it is much smaller than the Moon. In fact it turns out to be bigger than all of the other asteroids put together. Here’s an illustration of the first ten asteroids’ sizes against the Moon (in gray).
By convention, asteroids are numbered in order of discovery, hence 1 Ceres, 2 Pallas, 3 Juno, 4 Vesta, 5 Astraea, and so on. In the mid 20th century the numbers were still below 2000. Today the number is 1,382,205 (this includes other small bodies in the solar system, though, not just asteroids…but back then we had no inkling of such things). By the way when Pluto got demoted, it was instantly given the next number in the sequence, which back then was 134340.
Vesta, though much smaller than Ceres, is lighter colored, and technically it’s just barely visible to the naked eye…if you’re somewhere out in the middle of the ocean and eat a lot of carrots.
OK so what’s going on here?
At first, we had the notion that perhaps there had been a full-size planet there, but it had blown up or otherwise been destroyed. As it turns out, there’s not nearly enough stuff there. Now most astronomers believe that Jupiter’s gravity probably prevented a planet from forming there…so Kant was right.
With all of the other small bodies discovered more recently, asteroids are now defined as non-cometary bodies in the inner solar system (i.e., inside the orbit of Jupiter). Comets are largely made up of ice…not necessarily water ice…and will present a tail close to the sun. Asteroids, on the other hand generally fall into three categories, C-type or carbonaceous, M-type or metallic (iron-nickel plus other goodies), and S-type or silicaceous (rocks). They can be solid bodies, or in some cases, they’re basically piles of rubble, not even a single body.
Most asteroids are well-behaved, orbiting in the “asteroid belt.” It’s estimated that there are anywhere from 1.1 million to 1.9 million asteroids larger than 1 km there, and countless smaller objects. If you plot their semi-major axes (i.e., average distance from the Sun), the belt ranges from a bit over 2.1 AUs to 3.3 AUs. But there are gaps! Virtually no asteroid has a 2.5 AU orbit, nor one at 2.82 AU; they’re also scarce at a few other distances. Here’s what I mean:
These gaps are called the “Kirkwood” gaps, and the diagram gives a clue as to what causes them. In essence any body that orbits the Sun three times for each time Jupiter orbits once, will get perturbed–its orbit will change size–and will no longer be in that spot. This is a 3:1 resonance, and 5:2, 7:3 and 2:1 resonances also exist, and asteroids can’t be in those resonances for long.
This is not to say that no asteroid will ever be at that distance. If it’s in an elliptical orbit it could spend some time closer in than the gap, then farther out; of course it must cross through the gap.
Oh, and by the way: Forget what you saw in Star Wars or for that matter any of a hundred other space operas. Although there are a lot of asteroids…there is a lot more space. So it’s mostly empty space. Your chances of encountering one if you travel through the belt are miniscule…unless you aim for one. It’s certainly not the game of space dodgeball you see in Star Wars. (We’ve sent probes through the asteroid belt quite a lot.)
Asteroids Not in the Asteroid Belt
Not all asteroids live in the asteroid belt.
We have the Trojan asteroids. The first of these was discovered in the same orbit as Jupiter…but either 60 degrees ahead or behind Jupiter. These are actually stable places to be, according to work by Joseph-Louis Lagrange in 1772. (In general, any system with two large bodies orbiting each other will have stable locations at these locations, forming equilateral triangles between the two bodies and the locations; these are now called L4 (ahead of Jupiter) and L5 (behind Jupiter). Objects placed in orbits here will tend to stay there; even if they drift away, they’ll be pulled back, rather than pushed away, like a marble at the bottom of a bowl.)
As you might have guessed there are L1, L2 and L3 points but they are metastable; if an object starts to drift out of those locations, they will tend to move further away, like a ball set at the top of a hill.
The following diagram shows the Earth and Sun (not Jupiter and the Sun) complete with Earth’s moon; you can just ignore that.
The first such asteroids were named after heroes of the Trojan War, and this became a convention. In fact the ones at the Sun-Jupiter L4 point are named after the Greek side, while L5 denizens are named after people on the Trojan side. (However 624 Hektor (at L4) and 617 Patroclus (at L5) were given their names before the convention was established so they are in the “wrong” groups.)
It’s now estimated that there may be as many asteroids in these Trojan groups as there are in the “main” asteroid belt.
The term Trojan became standard for a body in any planet’s L4 and L5 points, and there are a few of these; in fact there are two in Earth’s L4 point.
But the more immediately–even urgently–interesting asteroids are the ones whose orbits are inside the asteroid belt. There are several groups of these Near Earth Objects…and that name should tell you why we are so concerned with them:
Amors (named after 1221 Amor) have an orbit larger than the Earth, and their minimum distance to the Sun is greater than Earth’s maximum distance to the Sun. As such, they pose no collision hazard with the Earth. Unless, of course, something mucks with their orbit, like a near pass with another body.
Atiras (named after 163693 Atira), their orbits are entirely within the Earth’s orbit. No hazard now, but the same caveat applies.
Apollos (1862 Apollo) and Atens (2062 Aten) are asteroids whose orbits cross that of Earth, in other words their furthest distance from the Sun either exceeds our minimum distance, and their minimum distance exceeds our maximum distance, or both. Apollos have an average distance greater than 1 AU, Atens have an average distance less than 1 AU.
Or there’s this handy-dandy chart you can use.
These are the scary ones. We are very, very aware of the consequences of a collision with a sizeable asteroid. Most life was extinguished by a 10 km asteroid 66 million years ago, and in historic times we’ve had two explode over Russia with megaton force (1908 in Tunguska and 2013 in Chelyabinsk)–and these were small bodies, roughly 50-60 and 18 meters across, respectively. Neither asteroid actually hit the Earth (at least not in one piece), rather they exploded high in our atmosphere when their trajectories grazed it.
50,000 or so years ago we did suffer a direct hit from a 50 meter iron-nickel meteorite, in Arizona. This left a 3900 foot crater you can visit today:
Note that we failed to spot the Chelyabinsk meteor before it hit, though we saw another one that completely missed the Earth not long before that.
We’ve bent considerable effort to trying to locate all Near Earth Objects and we think we’ve spotted the really big ones. But even a 100 or 50 meter object can cause a lot of damage, and no we haven’t spotted even a significant fraction of those.
Goodies
I mentioned earlier that metallic asteroids are made of iron and nickel, as well as other goodies.
This was important in the past, and will be again. Before we learned how to smelt iron around 1300 BCE (a very rough date, the end of the Bronze age), the only source of iron we had was meteorites. In fact, going back to the Trojan war, one of the gifts given to a Greek warrior was a meteorite he could use to make iron armor out of. Priceless! (Especially given that that particular mixture of iron and nickel is in fact much better material than pure iron would be.)
But what are the “other goodies”? We think these iron-nickel meteorites were once in the core of a larger body (not a full planet), which had melted and begun to differentiate, with the iron, nickel, and other heavy metals sinking into the core, leaving the outer layers relatively bereft of these metals. Earth has an iron core due to this very mechanism. We also have relatively little gold, platinum, PGMs, etc in our crust, because of this process. Although rare even in the core, they are less so there than up here.
Iron nickel meteorites do have some variances but are often 1 part per million or more of gold and/or iridium. This would be considered very good ores (especially for iridium which is normally less than a part per billion).
In fact it’s that relative abundance of iridium that was the smoking gun that established that an asteroid hit the Earth at about the time the dinosaurs were wiped out (there are still some holdout paleontologists who insist that most of the job was done by volcanic activity before the meteorite arrived). Sediments deposited at that time show “spikes” in the concentration of iridium.
That’s the past. What about the future?
We are pretty confident that 16 Psyche is a large iron-nickel body. It has been measured at 220 meters in diameter (it’s a bit irregularly shaped).
Its mass is 23 quadrillion (metric) tonnes. Or 23 million billion tonnes. That is a LOT of iron, more than we’ve ever used certainly, and…well, that’s going to be 23 billion tonnes of iridium, 23 billion tonnes of gold…but we can’t readily access it.
Yet.
We are sending a probe, named Psyche, to get a closer look and confirm what we think about it. It launched on 23 October of last year and is expected to arrive in 2029, shortly after the beginning of JD Vance’s first term as President.
Gold was as high as 2,670-something or so but then got hammered on Friday. Silver was over $32 even Friday morning, but the usual Friday beat-down occurred. Palladium’s bid price (i.e., the price they offer, not the price they ask) is lower than platinum’s bid price. (Usually when you see news stories about the price of these metals, they work off the bid price. I quote the ask price because you should be buying this stuff up, not selling it.) Silver again seems to be undergoing wider swings than gold, but the gold silver ratio ends up barely moving, somehow.
Gold futures contracts for December delivery apparently breached the $2,700 mark for the first time sometime on Thursday.
*The SteveInCO Federal Reserve Note Suckage Index (FRNSI) is a measure of how much the dollar has inflated. It’s the ratio of the current price of gold, to the number of dollars an ounce of fine gold made up when the dollar was defined as 25.8 grains of 0.900 gold. That worked out to an ounce being $20.67+71/387 of a cent. (Note gold wasn’t worth this much back then, thus much gold was $20.67 71/387ths. It’s a subtle distinction. One ounce of gold wasn’t worth $20.67 back then, it was $20.67.) Once this ratio is computed, 1 is subtracted from it so that the number is zero when the dollar is at its proper value, indicating zero suckage.

What is it that feeds our battle, yet starves our victory?
Speaker Johnson Pinging you on January 6 Tapes
Just a friendly reminder Speaker Johnson. You’re doing some good things–or at least trying in the case of the budget–but this is the most important thing out there still hanging. One initial block released with the promise of more…and?
We have American patriots being held without bail and without trial, and the tapes almost certainly contain exculpatory evidence. (And if they don’t, and we’re all just yelling in an echo chamber over here, we need to know that too. And there’s only one way to know.)
Either we have a weaponized, corrupt government or we have a lot of internet charlatans. Let’s expose whatever it is. (I’m betting it’s the corrupt weaponized government, but if I am wrong, I’d like to see proof.)
Justice Must Be Done.
The prior election must be acknowledged as fraudulent, and steps must be taken to prosecute the fraudsters and restore integrity to the system.
Nothing else matters at this point. Talking about trying again in 2022 or 2024 is hopeless otherwise. Which is not to say one must never talk about this, but rather that one must account for this in ones planning; if fixing the fraud is not part of the plan, you have no plan.
Small Government?
Many times conservatives (real and fake) speak of “small government” being the goal.
This sounds good, and mostly is good, but it misses the essential point. The important thing here isn’t the size, but rather the purpose, of government. We could have a cheap, small tyranny. After all our government spends most of its revenue on payments to individuals and foreign aid, neither of which is part of the tyrannical apparatus trying to keep us locked down and censored. What parts of the government would be necessary for a tyranny? It’d be a lot smaller than what we have now. We could shrink the government and nevertheless find it more tyrannical than it is today.
No, what we want is a limited government, limited not in size, but rather in scope. Limited, that is, in what it’s allowed to do. Under current circumstances, such a government would also be much smaller, but that’s a side effect. If we were in a World War II sort of war, an existential fight against nasty dictatorships on the brink of world conquest, that would be very expensive and would require a gargantuan government, but that would be what the government should be doing. That would be a large, but still limited government, since it’d be working to protect our rights.
World War II would have been the wrong time to squawk about “small government,” but it wasn’t (and never is) a bad time to demand limited government. Today would be a better time to ask for a small government–at least the job it should be doing is small today–but it misses the essential point; we want government to not do certain things. Many of those things we don’t want it doing are expensive but many of them are quite eminently doable by a smaller government than the one we have today. Small, but still exceeding proper limits.
So be careful what you ask for. You might get it and find you asked for the wrong thing.
Political Science In Summation
It’s really just a matter of people who can’t be happy unless they control others…versus those who want to be left alone. The oldest conflict within mankind. Government is necessary, but government attracts the assholes (a highly technical term for the control freaks).
His Truth?
Again we saw an instance of “It might be true for Billy, but it’s not true for Bob” logic this week.
I hear this often, and it’s usually harmless. As when it’s describing differing circumstances, not different facts. “Housing is unaffordable” can be true for one person, but not for another who makes ten times as much.
But sometimes the speaker means it literally. Something like 2+2=4 is asserted to be true for Billy but not for Bob. (And when it’s literal, it’s usually Bob saying it.) And in that sense, it’s nonsense, dangerous nonsense. There is ONE reality, and it exists independent of our desires and our perceptions. It would go on existing if we weren’t here. We exist in it. It does not exist in our heads. It’s not a personal construct, and it isn’t a social construct. If there were no society, reality would continue to be what it is, it wouldn’t vanish…which it would have to do, if it were a social construct.
Now what can change from person to person is the perception of reality. We see that all the time. And people will, of course, act on those perceptions. They will vote for Trump (or try to) if their perception is close to mine, and vote against Trump (and certainly succeed at doing so) if their perception is distant from mine (and therefore, if I do say so, wrong). I have heard people say “perception is reality” and usually, that’s what they’re trying to say–your perception of reality is, as far as you know, an accurate representation of reality, or you’d change it.
But I really wish they’d say it differently. And sometimes, to get back to Billy and Bob, the person who says they have different truths is really saying they have different perceptions of reality–different worldviews. I can’t argue with the latter. But I sure wish they’d say it better. That way I’d know that someone who blabbers about two different truths is delusional and not worth my time, at least not until he passes kindergarten-level metaphysics on his umpteenth attempt.

Gold has now busted $2600. Silver is going up but not quite enough to keep up with gold (it’s worth slightly less in terms of gold than it was last week). Palladium jumped up then back down this last week, ending virtually unchanged. But platinum is sliding. Rhodium is essentially stable.

That worked out to an ounce being $20.67+71/387 of a cent. (Note gold wasn’t worth this much back then, thus much gold was $20.67 71/387ths. It’s a subtle distinction. One ounce of gold wasn’t worth $20.67 back then, it was $20.67.) Once this ratio is computed, 1 is subtracted from it so that the number is zero when the dollar is at its proper value, indicating zero suckage.
Piling On
Just an Observation
The latest flerfer complaint is that the Final Experiment (the trip to Antarctica to observe the 24 hour sun) won’t count because it’s not an experiment but rather an observation. WTF? Anyhow, in this video, among many things of interest such as the fact that other people will be taking sun pictures that day in order to test the effect of variables (which would make it an experiment!), it’s shown what a bunch of lying hypocrite charlatans they are for trying to make this argument:
And this one from a year ago where Dave McKeegan tells of plotting the positions of celestial bodies over the Earth’s surface…then translating that to the pizzaworld model.
Antarctica
Oh, and spring (for Antarctica; it will be fall for Northern Hemisphere folks) starts at 06:43 Mountain Time on the 22nd (Sunday). This is the moment when the sun, which appears to travel along the zodiac line (even though we are orbiting it), appears to cross the celestial equator, northbound. [The celestial equator is just our own equatorial plane, projected out to infinity in the sky. The zodiac is the plane of the Earth’s orbit about the sun, projected out to infinity in the sky.] That should be the nominal instant when more than half of the sun becomes visible at Amundsen-Scott station at the south pole. (However, refraction makes the sun appear higher in the sky than it otherwise would, when it’s near the horizon, so sunrise will be somewhat earlier than this for them–and has probably already happened.)
So wish the 40 or so people who have spent the last six months wintering over there in either twilight or complete darkness a good “morning”!
Oh, wait…this doesn’t exist, does it? It’s all CGI!
In which case let’s get our money’s worth out of all that CGI, since we paid for it with our tax money. Here are a couple of videos which are tours of the station. First, upstairs.
Downstairs:
And there’s a part three (out of 2?) for the bits buried under the ice (such as vehicle maintenance, the generators, the logistics area, and so on); largely stuff that can get cold.
Incidentally there are three generators, that rotate, one is generally undergoing maintenance, one is a backup, the other is the active one. If all three crap out, there’s another generator that might manage to keep one part of the the station above freezing, but were this sort of failure to happen during winter over, they’re basically dead. It’d be easier to get people off the ISS then out of Amundsen Scott during winter.
And here’s one for the Ice Cube neutrino observatory (you’ll recall discussions of the neutrino in my Sun article a couple of weeks ago as well as during the physics series, part 20):
Anyhow, I hope you all enjoyed all that expensive taxpayer-funded CGI.
The 800 lb Gorilla
Jupiter, as photographed by the Hubble Space Telescope in 2017. A true-color image.
The single most important fact about Jupiter is that it is BIG. How big? Well let’s compare it to Earth and the Moon:
By size it’s 11 times the width of Earth; by mass it’s 318 Earths. That’s over 2 1/2 times the mass of all other planets, asteroids, comets, etc., put together. Or to think of it another way, you can characterize the solar system as consisting of the Sun, Jupiter, and miscellaneous debris. (And even with that Jupiter is barely 1/1000 the mass of the Sun.) To put it in absolute terms, Jupiter is roughly 88,000 miles across; and even the Great Red Spot–which is storm in the atmosphere–would swallow the Earth.
Ironically, if Jupiter were somehow even more massive, it probably wouldn’t be much larger. The gas would simply compress more to make up for it. The maximum diameter might be a bit more than what we see, but not much. If it were 75 times more massive, it would actually be compressed enough to start fusing hydrogen…and it might actually be the size of Saturn; considerably smaller than its actual diameter.
Jupiter has four major moons, three of them larger than our Moon, plus another 91 smaller moons, generally too small to be forced into a spherical shape. Those four big moons are at least as interesting as Jupiter itself and will be covered in a different article.
Jupiter orbits at about 5.2 AU from the Sun (and I’m not going to explain AUs yet again). That makes its “year”–the time to make one orbit about the Sun–11.86 Earth years. It has almost no axial tilt, so it doesn’t have seasons to speak of.
This is significant: It’s beyond the “snow line.” This means that a lot of things that would normally be vapor inside the line–like water–are solid outside. Hydrogen and helium, the major constituents of the matter that formed the solar system, are considerably cooler and easier for planets to hang on to; and Jupiter did just that; that’s fundamentally why it is so big.
Jupiter rotates on its axis in 9 hours, 55 minutes, and 30 seconds. That’s considerably less time than it takes Earth to do so (23 hours, 56 minutes, 4 seconds…with respect to the stars). Combine that with the fact that it is 11 times wider, and it turns out that an object on the Jovian equator experiences 65 times the centrifugal (well…it’s actually centripetal) force as an object on Earth’s equator. Why does that matter? It makes Jupiter look distinctly oblate (squashed); the difference between the diameter through the poles and between the equator is actually noticeable.
Jupiter is made almost entirely of gas and (deep down, under insane amounts of pressure somewhere between 500 and 4,000 atmospheres) liquid metallic hydrogen. Yes, under extreme pressure hydrogen behaves like a metal, complete with metallic bonds. And deep inside is a rock and ice core, that all by itself is larger than Earth. The following diagram is a cutaway of Jupiter. The pressures down there could be as high as 40,000 atmospheres, and the temperature is likely around 20,000K (versus 165K (-163 F) near the visible “surface.”
Unsurprisingly the atmosphere is mostly hydrogen (roughly 3/4), helium (a bit less than 1/4), plus a bunch of simple molecules like water (H2O), methane (CH4), ammonia (NH3), hydrogen sulfide (H2S), and even phosphine (PH3)…basically simple molecules made up of very common elements.
What we see is an “upper” cloud deck, but as it happens the light bands (called “zones”) are at a considerably higher altitude than the dark bands (called “belts”). The upper clouds made largely of ammonia ice are at a pressure of 0.6 – 0.9 Earth atmospheres, the lower visible clouds contain sulfur compounds as well as water ice and can be anywhere from 1-7 Earth atmospheres.
All of this implies that the atmosphere just above these clouds is already fairly thick, while being clear enough for us to see through.
That liquid metallic hydrogen has a significant consequence–Jupiter has a ridiculously huge magnetosphere. Since it captures charged particles, just like our Van Allen belts do here on Earth, that makes the entire Jovian system, including the Moons, very hazardous from a radiation standpoint. We can’t realistically send manned missions to Jupiter’s moons because of this, with the possible exception of the outermost of the large moons. It’s shaped something like a tadpole, with the head facing the Sun and the tail pointing away from the Sun. I haven’t been able to nail down the diameter of the magnetosphere, but it extends some 7 million kilometers towards the Sun, and the tail nearly reaches Saturn’s orbit. More info here: https://en.wikipedia.org/wiki/Magnetosphere_of_Jupiter
Like the Sun, Jupiter exhibits differential rotation, with belts and zones rotating at different speeds and vortices (including spots) showing up a lot on the boundaries. Here is a GIF made from a timelapse of Jupiter rotating as seen from Voyager I in the 1980s. The pictures are all taken at times when the Great Red Spot in the same orientation with respect to to the spacecraft, so you can see other features, which rotate at different speeds, change position with respect to the Great Red Spot.
Herding Cats
Jupiter’s great mass means that it often deflects smaller bodies in the solar system like comets and asteroids. Many comets have an orbital period that suggests that an encounter with Jupiter put the comet into that orbit in the first place. And Jupiter has even taken a bullet or two, most recently in 1995. The comet Shoemaker-Levy 9 was discovered having already broken into pieces thanks to tidal forces (yes, tidal forces show up again!) from Jupiter; it then was realized that Shoemaker Levy was going to impact Jupiter! What a spectacle! (And how good it was for us that it was Jupiter taking the brunt of that, not Earth!)
It wasn’t just a spectacle; the comet left “holes” in Jupiter’s atmosphere that allowed deeper material to come up to the surface where we could analyze the light with spectroscopes and learn more about Jupiter’s interior.
Jupiter is generally credited with reducing the amount of stuff that rains down on Earth from elsewhere in the Solar System.
History
Jupiter has been known since ancient times; it is generally the third brightest object in the night sky after the Moon and Venus. Since it is so bright and moves through the sky at a fairly stately pace, it got associated with the king of the gods, Zeus or in Latin, Jupiter.
It’s one of the ancient seven planets, each of which was associated with a metal, and each of which ended up associated with a day of the week. These are: Sun, gold, Sunday; Moon, silver, Monday; Mercury, mercury, Wednesday; Venus, copper, Friday; Mars, iron, Tuesday; Jupiter, tin, Thursday; and Saturn, lead, Saturday. And yes, the Sun and Moon were considered planets back then because they moved against the celestial sphere; the recent kerfuffle with Pluto is not the first time we’ve reclassified things. Many of our days of the week are named after Norse gods, but if you go to languages like Spanish, French or Italian, you’ll see the connections between days of the week and our planetary names (which, like those languages, are legacies of the Romans) more readily.
It’s a lucky coincidence that Jupiter turned out to be the king, not of the gods, but rather of the planets once we learned a lot more about it. This began mere months after we first turned telescopes to the sky; In 1610 Galileo noted four tiny “stars” near Jupiter, and could see the pattern change nightly, even over just a few hours. These turned out to be the four big moons of Jupiter (larger or comparable to our own moon).
The four big moons are to this day known as the Galilean moons, and you can spot them with binoculars. I said I’d cover them another time but there are a couple of points I want to make. First, when Galileo discovered them and realized they were orbiting Jupiter, that killed the centuries-old presumption that everything in the universe revolved around the Earth. (And if that wasn’t enough the phases of Venus put the final nail in the coffin, as they showed Venus revolved around the Sun.)
And our view of the universe was never the same again. That dinky telescope of Galileo’s (which is on display at a museum in Florence) is arguably one of the two most important telescopes in history for this reason. (The other being the 100 inch Hooker telescope that Hubble used.)
Second was their use in navigation. Galileo realized almost immediately that the moons’ motions were very regular; such that one could work up a time table and be able to tell absolute time with some accuracy here on Earth, provided you could see Jupiter and point a small telescope at it. Why was that a big deal? Because if you’re sailing a ship, the only way you can determine your longitude is by knowing what time it is in an absolute sense, or at least compared to some other location. For instance, if it’s noon in Greenwich, it’s about 7 AM in Washington DC….or perhaps some other spot in the middle of the ocean directly south of Washington DC. If you know both items of information; that the sun says it’s 7AM but it’s noon in Greenwich, England right now, you can figure out you are at 75 degrees west longitude. The problem was, they had no way of knowing what time it was in London at that same instant. We didn’t have anything like an accurate clock we could just set to London time (and never adjust it) to compare the local time to. But, we could look at Jupiter; if the moons were in the position for 3AM, you knew, regardless what time it was where you were at, that it was 3AM where the time tables were made. So you have a means of determining longitude.
But there was a fly in the ointment; it turns out that after painstakingly computing the table, it wouldn’t work well after a few months; the moons might get to their predicted position a bit early or a bit late. It turns out that the problem wasn’t with the computations, it was with the fact that sometimes Earth is a bit further from Jupiter, sometimes a bit closer, and so we were being thrown off by the light speed delay changing from one position to the other (light can take about 17 minutes to cross Earth’s orbit from one end to the other, and that’s about how much our distance to Jupiter varies). 17 minutes corresponds to about four degrees of longitude which in turn is 240 nautical miles if you’re near the equator. That’s a significant error!
We’ve also discovered that Jupiter has a very tenuous ring, a far cry from Saturn’s ring system, but there nonetheless.
Spacecraft
Jupiter is visited often by our spacecraft, not only for its own sake but because it’s a good waypoint for other missions; it’s often used for a gravity assist. The New Horizons probe to Pluto used a gravity assist from Jupiter to shorten its flight time by about five years (it could have got there without the assist, which in itself is remarkable).
The first probes were Pioneer 10 and 11 in 1973 and 1974. It was the Pioneer spacecraft that discovered Jupiter’s magnetosphere. (Pioneer 11 went on to Saturn). In 1979 Voyager 1 and 2 paid a visit, these spacecraft both went on to Saturn and one of them went on to Hugh Janus and Neptune.
Ulysses, which was a mission to study the sun, flew by Jupiter in 1992 and again in 2004. Why send a solar probe away from the sun to Jupiter? Because we wanted to put the probe in a highly inclined orbit so we could see the Sun’s north and south poles for the first time. The easiest way to do that was to send Ulysses past Jupiter’s north pole and let Jupiter bend the orbit into the new plane, some 80 degrees off from the main plane of the solar system. (Jupiter will bend your trajectory no matter what, but if we approach Jupiter so as to pass the pole, the trajectory will be bent outside of the plane of the planets’ orbits.) If we hadn’t done that we’d have needed a gigantic delta-V to cancel out Earth’s motion around the sun (which the spacecraft would “inherit”), then more to put the spacecraft into its new orbit around the sun. Ulysses took these opportunities to study Jupiter’s magnetosphere.
Cassini flew by in 2000, on its way to Saturn.
Flybys are great, but an orbiter is better. We sent the Galileo orbiter to Jupiter, with it arriving in 1995 and sending back data, including from close encounters with the four Galilean moons, until 2003. Galileo was well timed–when comet Shoemaker-Levy impacted Jupiter Galileo was approaching the system and took some amazing pictures of the aftermath of the event (the impacts were unfortunately on the far side). Galileo came with an atmospheric probe, too, that was dropped into Jupiter’s atmosphere on a suicide mission to return data for as long as it could withstand the rapidly-increasing pressure. In 2016, Juno, a European spacecraft, arrived at Jupiter, establishing itself in a highly elliptical and inclined orbit which means that once every orbit it gets very close to the clouds, and it passes over the poles, which otherwise we’d never see. Juno is still active.
Life?
Jupiter is sometimes cited as a possible location for life. In this case, since it’s essentially atmosphere down to depths where the pressure is crushing, the life forms are generally imagined as creatures with huge bladders filled with atmospheric gas…basically living hot air balloons. This idea got kicked around a lot, including by science fiction writers (like Arthur C. Clarke; a much more recent story told of Jovians’ reactions to Shoemaker-Levy 9).
All of this is complete speculation, of course, and I think as we’ve learned more about the rest of the solar system, we’ve come up with better candidates. But in the end we probably don’t know enough to even intelligently decide which scenario is most likely.
