Six planets in coordinated orbits

https://youtu.be/KfZCGBhwpes In my personal opinion, one of the mathematically coolest things in our solar system is the orbits of Jupiter's three inner Galilean moons. It just happens, that these worlds orbit to a beat, with innermost Io circling four times for every...
