Orbital is a planetary orbit simulator for Mac OS X. It's designed for beginning physics and astronomy classes, but is also strangely fun to play with. The simulation uses an approximation of Newtonian gravity, which, while not accurate enough for planning your next shuttle launch, is plenty accurate for most other uses.
