Welcome to JOrrery!
N-body Simulation Applet
JOrrery simulates the motion of planets moving under gravity. It comes with a number of initial "scenarios" you can run, such as "The solar system", "Earth & Moon" etc and you can load and save your own scenarios in xml format. You can also add more planets during a simulation. JOrrery allows you to create a number of different views on the universe, either as graphical views focussed on different planets, or text views giving the planets' co-ordinates in space.
