Where did you hear about the moon's atmosphere? I try to keep up on Astronomy
news, but I've heard nothing about it. It can't be pure sodium, as I'm pretty
sure the moon's gravity isn't strong enough to hold it (although I may be
wrong).
Also, the orbital distance will determine what a planet's atmosphere is like.
The elements settle out at different distances from the star they orbit, which
is why the first four planets are composed primarily of heavy elements and
compounds (iron, silicon), and the second four are composed primarily of light
elements and compounds (helium, hydrogen). Pluto is, of course, an anomoly.
