Simulate stars, planets, and their gravitational interaction.
You have a visualize window and a control panel window. You can use the "Random" option to let the program generate a random number of stars, within certain mass, velocity and position ranges that you can set. Or you can specifically set initial position, speed and mass of a fixed number of stars / planets and simulate your own mini solar system.Also there are a few options to set the internal G constant, view position and perspective correction to the visualize window.
