In turn, the lack of water caused Venerean plate tectonics to fail, causing Venus to have periodic "resurfacing" events where the entire crust is recycled by volcanism. On top of that, Venus was almost certainly hit by an enormous object, hard enough that its spin was completely reversed. Randall may be saying that Venus has fared so badly throughout its life that it deserves some compensation, like rings or a moon.

 Alternatively, Randall could be referring to how we see Venus now as opposed to in the past. A hundred years ago, 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 a little colder. However, when we sent spacecraft to Venus and Mars in the 1960s, we quickly discovered that [https://what-if.xkcd.com/30/ Venus is a terrible place]. Its atmosphere is more than 90 times as dense as Earth's and its surface temperature is over 450° C (800° F), not to mention the sulfuric acid rain. Spacecraft that have landed on its surface have lasted a couple hours at most. As a result, missions to Venus have become far rarer since the 1960s, while missions to Mars have remained frequent. Randall might be saying 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.

 | More asteroids! || Asteroid belts are usually portrayed in fiction as being incredibly crowded with asteroids, so much so that they pose a significant hazard for spaceships.

They proposed a hypothetical planet, {{w|Vulcan (hypothetical planet)|Vulcan}}, to account for this discrepancy. After general relativity was discovered by Albert Einstein in the 20th century, it was found to account for these discrepancies.

 In the 17th and 18th centuries, some astronomers (most notably Giovanni Cassini) claimed to have found a {{w|Neith (hypothetical moon)|moon of Venus}}, but that was later determined to be an illusion.
-Note that, due to the retrograde spin of Venus, any prograde-orbiting moon would be inspiral due to tidal drag (the same effect causing the Moon to slowly move away from the Earth). It is unknown whether Venus used to have moons that were destroyed by this mechanism (possibly passing through a ring state in the process).

-| Replace our moon with Mars. Mars is more interesting and we can consolidate missions. || Mars has a lot more geological variety than the Moon, a much faster rotational period, and is much larger and has weather patterns, and would therefore look far more interesting than the Moon when seen from Earth. In addition, by replacing Earth's current moon with Mars, sending spacecraft to the moon and Mars wouldn't require separate missions and could thus be consolidated into a single one.  This would benefit NASA's space exploration efforts, which have suffered from presidents alternating targets for human exploration between "moon-to-Mars" versus "Mars direct" architectures.

-Unfortunately, replacing our moon with Mars would have some negative side effects worlds. Mars is 8.7 times more massive than the moon, which means that it would raise much stronger tides on Earth than our moon does now. As for Mars, it would now be significantly warmer than in its present orbit. The ice caps would likely sublimate, and what little water is left on the planet could boil away due to the lack of a thick atmosphere (Also, Mars would probably crash into Earth.).

 Incidentally, the Moon is thought to have been formed by an impact between the young Earth and a Mars-sized body. While Randall probably means well, the situation could get out of control very quickly.

 Interestingly, 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, while Triton remained with Neptune.
