Gravity (software)

This article is about the planetary motion simulator. For other software, see Gravity (disambiguation).

Gravity is a software program designed by Steve Safarik^[1] to simulate the motions of planetary bodies in space. Users can create solar systems of up to 16 bodies. Mass, density, initial position, and initial velocity can be varied by user input. The bodies are then plotted as they move according to the Newtonian law of gravitation. Simulation settings may be saved as files with the extension ".GRV".
