Talk:Icy moon

Comments
Where 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

 * "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)

By "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
