Binary star systems also have an orbital resonance, referred to as a Binary Star orbit, around the 'center of mass of the system'.
There are also solar system orbital resonances and lots of them.
It is perhaps how our solar system maintains its structure and all the orbit resonances.
Are the orbital resonances of asteroids, moons, planets, stars and solar systems a circuit? A way to keep energy balances or transfer energy between them through touching plasmaspheres and other electromagnetic forces?
Planets orbital resonance
Planets and moons in our solar system have orbital resonance. Even planets and asteroids have forms of orbital resonance.
The most famous are Jupiter and its moons - Ganymede, Europa and Io. You also have Neptune and Pluto, Titan and Hyperion, Dione and Enceladus.
stars and binary stars orbital resonance
The Eta Carinae system has binary superstars in an orbital resonance.
