I love these sort of things...

Fascinating - but what it does demonstrate is how difficult it is to make a stable 4 body system, with collisions (and sometimes bodies getting kicked out of the system) creating attrition until you have left only a stable 2 body system.  Given the thousands (probably millions) of bodies within our solar system (with 8 of them large enough to still be classed as planets), it must be an indication of how large the attrition rate must have been in the early solar system, and even now, how high the probability must be of regular collisions occurring.

George - that's a very sobering thought.

Take one of the preset multi-body orbits (for instance, the 4 ballet star).  See how the orbit works in a totally stable fashion.  No just alter the mass of one of the components (e.g. change it from a mass of 120 to a mass of 121), and see what changes it makes to the orbits.

Thanks for that link doc. Ben and I sat at school messing with that thing all day trying different things.

This is brilliant!

Is that how our moon really revolves around the Earth? It's actually revolving round the Sun, but it's path is distorted that way by the Earth's gravitational pull?

Yeah George, I just crashed the moon into the sun on the first orbit. Didn't make even a half a rotation.
