Fascinating app – Gillian's Planets - Orbital Planet Simulator and Screensaver Review

I downloaded this last night and spent about an hour experimenting with it. Found that random assortments of planets around a star are usually unstable - the smaller planets often are ejected out of the system or go into very eccentric orbits, like comets. Gives me an appreciation for how lucky we are to be in a stable solar system - and how the alignment of orbits may have been very different in the past - as is currently theorized. It appears very difficult to arrange a stable system with more than 3 bodies. There are enough color and sound schemes available to provide variety. Thanks to "Gillian" for making this app available!
