- 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. It 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.
