Composition of planets vs. moons

[Loren Booda]

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! :smile:

Surely there are no "gas moons"? :confused:

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.
