Composition of planets vs. moons

Loren Booda · Dec 26, 2010

In our Solar System, how does the ratio of gas planets to terrestrial planets compare with that of gas moons to terrestrial moons?

Hi Loren Booda!

Surely there are no "gas moons"?

Well gas planets to terrestrial planets is obviously 1:1 and gas moons (i.e moons around gas planets, tim) to terrestrial moons is like 165:3.

There appears to be no correlation at all. Oh well.

Sorry. Are there no liquid moons? That is basically what I meant by "gas moons."

I believe all solar system moons are believed to be rocky.

That includes a few that have thin oceans above the rocky surface.
