Celestia is a free 3D astronomy program. Based on the Hipparcos Catalogue, it allows users to display objects ranging in scale from artificial satellites to entire galaxies in three dimensions using OpenGL. Unlike most planetarium software, the user is free to travel about the Universe.
This is a dummy package that selects at least one frontend for Celestia.

The free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.
Unlike most planetarium software, Celestia 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.
All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit.
Celestia is expandable. Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that's not enough, you can download dozens of easy to install add-ons with more objects.

The 1989 flyby of Neptune by Voyager 2--last stop before leaving the solar system.
Saturn and its rings. Dark shadows cast by the rings are visible in the top hemisphere of Saturn.
Jupiter and its large moon Europa. The surface of Europa is mostly water ice and full of cracks created by tidal stresses.
The recently discovered extrasolar planet Rho Cancri e, one of a system of at least four planets. Rho Cancri b is visible just to the right of e.
