Celestia is a freeware program that
doesn't confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.Some folk have written Celestia scripts which will show you what the night sky would look like from an exoplanet (including where in the sky is our sun). For example, Ian Musgrave of Australia has written a script that takes you on a tour of three exoplanets (including showing you what the night sky would look like in the direction of our sun). It can be found in his Astroblog: A Tour of the Exoplanets in Celestia post.
