| Proposed change
| Add mysterious planets inside Mercury's orbit
|| In the 19th century, scientists found discrepancies between Mercury's predicted orbit and observations. They proposed a hypothetical planet, Vulcan (hypothetical planet), to account for this discrepancy. After general relativity was proposed by Albert Einstein in the 20th century, it was found to account for these discrepancies.
| After what it's been through, Venus deserves rings and a moon
|| In the past, scientists considered Venus and Mars to be equally likely candidates for life and future human exploration - one being a little warmer than Earth, and the other being a little colder. However, when we finally sent spacecraft to Venus and Mars in the 1960s, we quickly discovered that Venus is a terrible place[]. Its atmosphere is more than 60 times as dense as Earth's, crushing all spacecraft that land on the surface - not to mention the sulfuric acid rain and temperatures hot enough to melt lead. As a result, missions to Venus have become far rarer since the 60s, while missions to Mars have remained frequent. Randall probably thinks that most people don't consider Venus to be nearly as fascinating place as they used to, and that it would be far more interesting with rings, or at least a moon like Earth or Mars.
| Replace our moon with Mars. Mars is more interesting and we can consolidate missions.
|| By making Mars a "new" moon of the Earth, missions to the moon and Mars wouldn't require separate spacecraft, and could thus be consolidated into a single mission.
| The solar system needs a super-Earth
|| Super-Earths are a type of exo-planet that have been identified orbiting stars other than our own.
| More asteroids!
|| Asteroids belts are usually portrayed in fiction as being incredibly crowded with asteroids - so much so that they pose a significant hazard for spaceships (or a challenging set of obstacles in a video game). In reality, the asteroid belt is much more boring - most asteroids are hundreds of miles from their nearest neighbor.
| Merge the big planet and the ringed planet into a big ringed planet ("Jaturn")
| Cut Uranus. Uranus and Neptune are redundant and Neptune is better. Tough but fair.
|| Uranus and Neptune are often regarded as being planetary "fraternal twins." Both have approximately the same size, the same mass, and the same composition - they even have similarly bizarre magnetic fields. Randall likely considers Uranus to be less interesting than Neptune because it looks completely bland most of the time, while Neptune has more active weather patterns.
| Settle the planet thing by making Pluto a moon of Neptune
|| One of the original hypotheses for Pluto's origin is that it and Triton were originally both moons of Neptune, but Triton knocked Pluto out of its orbit into a new orbit around the sun.

What Venus has been through
- For "what Venus has been through" see  22.214.171.124 19:44, 22 January 2020 (UTC)
I feel like the transcript is unnecessary because it's wholly redundant with the table here. Anyone object to merging the two sections? 126.96.36.199 20:45, 22 January 2020 (UTC)
- See the transcript for State Borders. I think we still need to have a transcript, since the locations of the arrows and other marks aren't made clear in the table. 188.8.131.52 20:57, 22 January 2020 (UTC)
- We always need the transcript. There should be no explanations in the transcript. It is both for people who need it to "read" the comic, and to be able to search for text from comic. Also the description of the image is relevant, in case there could be misunderstandings of what is on the image. If the transcript gets that wrong, then it can be debated and corrected. --Kynde (talk) 12:54, 23 January 2020 (UTC)
Note that in future, we may be actually able to implement some of those changes ... however, at that point the consolidation of missions to Moon and Mars wouldn't be relevant :-). Also, I would be against: most of those changes would be likely to make our solar system considerably less stable. Except Venus would really deserve some moon. Just small one, it doesn't need to be as big as ours. Also, we should light up Jupiter, to warm it's moons (this is one of Clarke's ideas). -- Hkmaly (talk) 00:37, 23 January 2020 (UTC)
- If Venus god a Moon it would most likely quickly be ejected by the interactions of the Sun, it is too close to the Sun not to see it as a three body problem, and that will always be chaotic. --Kynde (talk) 12:54, 23 January 2020 (UTC)
- "Quickly ejected" is probably an overstatement; even Venus has a significant Hill sphere, and any significant moon would first spiral inward due to losing tidal energy "spinning up" the rotational velocity of Venus (a huge benefit!). the Sun would probably act to make the moon's orbit eccentric & it could either crash into Venus or get ripped away, but I give it half a billion years or more. (but with a bit of curation the moon could give Venus a nice 24 hour day, and with that a magnetic field, who knows!) 184.108.40.206 15:40, 24 January 2020 (UTC)
Wow - I only just noticed that "Jaturn" has Saturn's hexagon at the top. Should this be highlighted in the table? After all, it is cool science: https://www.smbc-comics.com/comic/2010-07-06 220.127.116.11 02:04, 23 January 2020 (UTC)
- Yes, has already been done. --Kynde (talk) 12:54, 23 January 2020 (UTC)
I don't think the title text has anything to do with anthropomorphism. Rather, there is a person near R. just then who knows stuff about Jupiter. 18.104.22.168 03:44, 23 January 2020 (UTC)
- The title text is Randall relaying a quote spoken by someone other than himself, with that person's identity "signed" after the two dashes (kind of like how we usually sign posts with --~~~~). Therefore, it is properly read as "someone (who knows Jupiter is within earshot)", not "(someone who knows Jupiter) is within earshot". If Randall had meant the latter, he would more likely have written something like "To the Jupiter fans: of course Jupiter already has a very impressive ring system!" --NotaBene (talk) 04:44, 23 January 2020 (UTC)
- You are correct. The two dashes are indicative of signing a comment. Had Randall intended to comment that someone who knows Jupiter is close by, he would have put the comment in parentheses. 22.214.171.124 18:59, 23 January 2020 (UTC)
- He may also refer to the God Jupiter, who is the God of sky and thunder, and may easily smite anyone offending him. --126.96.36.199 07:42, 23 January 2020 (UTC)
- I agree with the first commenter: This is not about anthropomorphism. This is someone who states that Jupiter already has rings, and Randall comes those in advance by mentioning it in the title text. Annoying people who cannot see the difference between Saturn's Rings and other ring systems! --Kynde (talk) 12:54, 23 January 2020 (UTC)
- Honestly, I originally read the title text, got confused due to its wording, and went with the second interpretation ("a Jupiter fan is within earshot and knows about its rings"). However it didn't quite feel right, and reading it again, the first interpretation ("a person knows that an anthropomorphized Jupiter is within earshot and wishes to placate him") makes just as much sense - in fact, grammatically, it makes more sense, since otherwise you have to suppose that Randall intended this weird combination of speech attribution and stage direction. However, it makes less sense in context, since the comic is talking about real planets and didn't mention gods or anthropomorphized planets at all. Randall simply seems to have been clumsy with his wording. Hawthorn (talk) 09:58, 24 January 2020 (UTC)
- The joke is that nobody actually thinks Jupiter's ring system is all that impressive, and the only person who would say that it is impressive is literally concerned that Jupiter itself can hear them. If Randall had meant someone who knows about Jupiter, he would not have left out the word "about" (not to mention he would have formatted the title text differently). 188.8.131.52 18:35, 24 January 2020 (UTC)
Someone needs to make a Kopernicus mod in KSP and load it with Principia to see how long it lasts. Assume scales are close to the real one. 184.108.40.206 (talk) (please sign your comments with ~~~~)
This comic may alternatively be about climate change - something about satire, metaphors, acid rain, super-Earths, current-events, the nature of rings surrounding planets & extinction level events. I don't know. Don't listen to me. 220.127.116.11 (talk) (please sign your comments with ~~~~)
- We won't. Sure Randall makes those comics, but this is clearly not one of them. (oh and please sign you comments ;-) --Kynde (talk) 12:54, 23 January 2020 (UTC)
Oh please won't someone calculate the extent of low and high tides if we replace the Moon with Mars? Cellocgw (talk) 15:15, 23 January 2020 (UTC)
You know, for all my complaints about the Solar System, I always thought Jupiter and Saturn were well-balanced. Each of them has something interesting about it, and we don’t get too much of an overload of features from either one. In order to maintain variety while keeping the number of gas giants to a minimum, I think Neptune should get the rings. Jupiter can keep the moons, though, and otherwise I support this revision. —18.104.22.168 19:53, 23 January 2020 (UTC)
- Actually, Neptune already has a very impressive ring system!22.214.171.124 10:28, 24 January 2020 (UTC)
- It's gone now, you can be honest. 126.96.36.199 22:07, 24 January 2020 (UTC)
Can anyone make an educated guess about which of the changes, if implemented individually, would have the largest impact on the solar system as a whole? I'm guessing the largest impact on humans would be the mars-moon thing.Bischoff (talk) 11:20, 25 January 2020 (UTC)

"Jaturn" seems the lean too heavily of Saturn for the name, giving Jupiter short-shrift, and we all know what a bitch Jupiter can be (see title text). The name should be "Jupurn". 184.108.40.206 16:35, 30 January 2020 (UTC)
