Yes, Sterling, as Larry mentions, carbonaceous chondrites have been proposed as questionable yet decent matches for Ceres, though others add that primitive achondrites are where it is at and that the biggest inner minor planet is somewhat differentiated. Looks like there aren't any especially prom

Hello Sterling: As TNOs are already a term in science lit, we're covered (and cryosilicates doesn't throw Pluto a bone). Or KBOs work too, as mentioned. Frigophile might amuse some, but as you say, it is technically sound, too. Here's an aside on Uranus: it's the only Greek-named planet of the n
