It's a space simulator that will allow you to change and rearrange all the objects and to move planets, stars, comets, and anything else in space to the locations you desire.
Well, good news for you: The Universe Sandbox 2 program allows you to do exactly that. So for every space fan out there, he or she has probably wished at one time to play around with the universe and all its luster, much like kids in a sandbox. Some continue to go to these events and exhibits even as adults. Most people took that proverbial field trip as a little kid to some planetarium, where they got to see the stars and all the planets in a way they've never seen them before. If you're a space buff and enjoy the solar system, galaxies, planets, stars, etc, then you'll probably love Universal Sandbox 2, as it allows you to tinker around with the universe and display the objects how you want to see them.
