Planets is a fun, interactive program for many-body gravity simulations. The emphasis is on play: it's easy to add in planets, zoom in and out, change the physical constants, save and load configurations, etc. It's designed to be easy enough for a kid to enjoy, but that hardly precludes adults.

Release Notes: Traces were fixed so that they no longer fail with recent versions of Tcl/Tk.
Release Notes: The makefile and .spec file were cleaned up. A "-debug" command line option was added to turn on debugging messages, which is useful for figuring out what the right keysym is for a certain key. The zoom in/out was fixed so it works with the keypad. A manpage is now included.
Release Notes: A fix was made for the Danish translation.
Release Notes: The biggest change is the inclusion of a 4th order Runge-Kutta simulation. Planets is now far more accurate than it was, even at a much courser grain of simulation. A few other cleanups of the interface have been put in, as well as a desktop entry and icon.
Release Notes: Addition of random orbital planet improved to avoid slingshotting effect, which improves kid mode considerably.
