You could try Celestia. I remember having a lot of fun using that program. Not sure how accurate some of it is, my Last astronomy course was several years ago and I haven't really kept up and only found the program a year or so ago.

Cyrien, you are currently my hero. Between the info I got from Henk, the new toy I have in Celestia, and the new patch on Diablo II: LoD I will be happy for days.
I long to see Europa. Those Icy oceans... skies filled with carbon and sulphur... I miss there... *snif*
