|
|
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.

|
2009-08-16 16:48:30 +00:00
|
|
|
spacecraft only a few meters across. A "point-and-goto" interface makes it
|
2008-04-29 07:55:23 +00:00
|
|
|
simple to navigate through the universe to the object you want to visit.

Celestia is expandable. It comes with 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.
