From the developer:
Gravity Simulator provides amateur astronomers with a powerful numerical integration tool. By performing n-body simulations, you can study the orbits of planets, moons, asteroids, or any object in the universe. You can recreate simulations performed by professional astronomers, or experiment with simulations of your own creation.
