It's really nice. Be sure to activate paths, I'm having a lot of fun using that to draw cool stuff :). https://i.imgur.com/j3YwI5y.png https://i.imgur.com/j3Yw

That was me trying to have a small particle making an 8-shaped path around two bigger ones that would be sufficiently far apart to not interact too strongly with each other. Of course, when the small particle went between the two bigger ones, it shifted their position a tiny bit, but sufficiently for those two to start very slowly moving towards each other, while the small particle was headed straight to the up-right direction. But when the two bigger particles became close enough to finally meet and become one single huge particle, it attracted back the small one, which since then goes back slowly to the huge particle only to shift it a bit and be "relaunched" by it for a new lap. The system seems to be totally stable that way.

This kind of path is called a free return trajectory and was used in the Apollo program lunar missions. The trajectory is not periodic, ie. it doesn't repeat more than once. The trajectory around the earth takes less time than lunar period ("month") so when the craft goes back up, the moon has moved on. You might be able to construct a planet-moon system with an m:n resonance in the orbital periods of the moon and the craft so that the tracjetory is periodic. Free return trajectories are used in manned space flight to guarantee that the craft and crew return to earth if a failure prevents from entering lunar orbit.
