i would have to say saturn, it is the only planet that would float on water, it has sweet rings and it has a coo name. but second would be Mars, because if it just warmed up a little there would be water
i believe you are naming a moon. Moons aren't planets! :s
Hehe.
My favorite planet is this one, since the rest are inhospitable hellholes. Aside from that, I think Mars and Saturn. Mars doesn't have the brutal atmospheric pressure that would quickly kill a person, so it is possible for someone to land there and explore in a suit.
Obviously, it's Earth, since it's known to be the only planet to support organic life. Apart from Earth, I think Neptune takes the second place since it's bluish-green due to its methane rich atmosphere.
Pluto. Oh, wait, that's not a planet anymore, is it? In that case, my favorite planet is Venus. I go there during the winter when it's too cold on earth.
