editWhere are the icy moons in the solar system? What are they called? How did they get there? What do they tell us about solar system evolution? — Preceding unsigned comment added by 81.152.52.152 (talk • contribs) 17:53, 21 January 2007 (UTC)
Not all belong to giant planets
edit- "All known icy moons belong to giant planets, whose orbits lie beyond the Solar System's frost line."
I believe this is wrong because Charon is also an icy moon and does not belong to a giant planet, but to the dwarf planet Pluto. --Neitram (talk) 11:31, 26 September 2014 (UTC)

editBy "ice", do we necessarily mean water ice? What about other elements in ice form, such as dry ice, nitrogen or methane ice? --Neitram (talk) 11:33, 26 September 2014 (UTC)
Yes an "icy moon" could refer to CO2 , nitrogen, etc. But the predominant form of ice just about everywhere in our Solar System (even on Mercury!) is water or water-based (e.g. clathrates). Olthe3rd1 (talk) 11:49, 9 January 2016 (UTC)olthe3rd1, 9 January 2016
