Commented on Blogging for Orbit
Ok, I've got a minor, annoying, nitpicking quibble. Planet detection by both radial velocity and transit light curves are biased toward finding planets that are big* and near their primaries. (Big meaning more massive for radial velocity and larger diameter...

Two bodies yes, but it's not like the Moon is (or is a remnant of) the impactor. Impactor hit the Earth, two mixed together, some of the resulting mixture splashed up and became the Moon. Moon's isotope ratio is not the same as that of [i]primordial[/i] Earth, but same as resulting Earth....

Natural uranium on Earth contains more like 0.7% U-235 rather than 0.2%, so Shin-Tethys uranium at 1% is richer in U-235 than natural uranium than Earth but not by that much. If we apply the implied correction factor to real isotopic abundance (U-235 is 5 times more abundant on Shin-Tethys relative to Earth) then we get natural uranium at 3.5% U-235 on Shin-Tethys, ready to fuel a light water reactor or a blue smoker without further enrichment. /isotope-pedant...
