A simulator for kepler orbits given orbital state vectors and relevant constants.

Kepler Orbit Simulator 2D is a processing for android app that allows the user to simulate a kepler orbit neglecting the mass of the orbiting body, defining their own values for relevant constants such as G as well as other parameters. These include simulation speed, the mass of the central body, and the orbital state vectors, velocity and position. The radius of the bodies being drawn can be adjusted for aesthetic purposes as well.
