The free space simulation that lets you explore our universe in three dimensions.
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.
