Publisher's description
Celestia is an application for real-time 3D visualization of space, with a detailed model of the solar system, over 100,000 stars, more than 10,000 galaxies, and an extension mechanism for adding more objects.
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.
