    I don’t know if we have enough evidence to make such claims tbh. In our solar system, half the planets are rocks with a metal core (riffs playing in the background), the other half are gas giants. Among the gazillion moons though, there are some ice moons (like Titan and Europa), Venus only has no oceans because it is too hot, Mars has a volcanic past and may be warmer had it a thicker athmosphere and has polar ice caps, etc. There is a lot going on on these “barren rocks” and a lot of them being barren rocks could be due to them being located outside the goldilock zone.
