[Request] Inner Planets

I'm designing a space map, and need various appropriate models. Most importantly, I need models of the Sun, the Moon, Earth, Mars, Venus and Mercury, preferably with accurate texturing.

They can all be based on the same spherical model with different textures, and should be the same size so I can accurately scale them in-game. They shouldn't rotate as a default animation (once again, so I can control rotation in-game).

Venus shouldn't have a visible surface, since it doesn't, so it can have layers of revolving clouds or just a solid texture. Earth can have layers of rotating cloud-bands, as long as the surface is visible and immobile. The Sun should have an animated corona, and an orange-and-yellow texture like this.

I remember having seen an Earth model on the site somewhere some months ago, but I couldn't find it when I went looking for it. If someone knows about it and can link me, that'd be much appreciated.
