AstroGrav is astronomy software that allows you to simulate how astronomical objects move and interact under the force of gravity. It features superb interactive 3D graphics which allow you to move around within a many-body astronomical system, while watching how it evolves with the passage of time. A wide variety of sample files are provided, and comprehensive editing facilities allow you to create and modify your own astronomical systems.
