Ah, so a captured body would be quite different and alien. Really old too. Like, first generation of stars.

- s1artibartfast 1y agoNot at all implied. It could be boring and younger too. 10x earth masses usually implies a gas giant.

- geuis 1y agoWould likely be older than the solar system itself. Probably not first gen star old, but likely would have formed before the sun did. Don't know how different it would be though. Would have formed out of maybe different ratios of elements than what was in the molecular cloud we formed from, but otherwise a large body like this would have undergone similar geological processes as our own planets.
