Celestia

A free, open-source real-time 3D space simulator that lets the user fly beyond the Earth's sky to visit the planets, moons, stars, and galaxies, viewing the Solar System and beyond from any vantage point. Unlike a planetarium fixed to the ground, Celestia treats space itself as the stage.
