The Galilean moons get less dense in sequence as one gets away from Jupiter. This is usually explained by primordial heat from young Jupiter creating a strong radial temperature gradient that vapourised the volatiles especially on Io and Europa, IIRC. (Tidal heating probably helped too, I guess.)
However, the large satellites of Saturn and Uranus don't show any such trend. Is the explanation for this known yet? Double sharp ( talk) 03:04, 21 July 2021 (UTC)
