Algodoo

An interesting study into the effect of gravity on matter in space. Watch how the different masses of object bend your planet (the red dwarf you follow) in it's course through the voids of space. See magnificent binary orbits of large stars or join a cluster of planets and watch open orbits or passing comets. A journey through the void of space.


Notice how large clusters of stars are less stable (more mass less stable, important fact, learn it!) and often chuck out smaller stars while spinning round gathering up planets. The most stable clusters are the ones of small planets in twos which harmlessly spin round each other in a perpetual dance. Avoid the clusters! They are boring to be stuck in and you might not be coughed out into a different orbit.

Enjoy
