celestia 1.3.2-3.1ubuntu1 (amd64 binary) in ubuntu dapper

 Celestia is a real-time visual simulation of space. Choose a point
 within the Local Group of galaxies, and Celestia will show you an
 approximation of how it would appear to your eyes were you actually
 there. Some of what Celestia shows is necessarily hypothetical--the
 farther away from Earth you get, the less real data there is and the
 more guesswork is involved. Thus Celestia supplements observational
 data with good guesses based on models of stellar and planetary
 processes.
 .
 Celestia is unique in its ability to allow you to navigate at an
 immense range of scales. Orbit a couple kilometers above the surface
 of a tiny, irregular asteroid, then head off towards Jupiter, watching
 it grow from a bright point of light into a looming sphere filling your
 field of vision. Leave our solar system entirely and observe the sun
 as it fades from a brilliant disk to a bright star, disappearing almost
 entirely as you head off toward the Upsilon Andromeda system to orbit
 around its innermost giant planet.
