There are orbital resonances, but you are right that none involve planets. https://en.wikipedia.org/wiki/Orbital_resonance The closest is the 2:3 ratio of Pluto:Neptune. (It counts if you consider Pluto a planet. ;) Otherwise, there's a nice table showing "near-integer-ratio relationships between the orbital frequencies". If I understand it correctly, each of the bigger-than-a-dwarf-planet planets will be at their furthest possible distances from each other in timescales no longer than about 50,000 years. |
