Physics, Astronomy & Cosmology / How many levels of orbit can a planetary system sustain?
« on: 31/07/2022 20:10:08 »
I know about planets orbiting stars, and moons orbiting planets. My question is if it's possible to go further than that: are there stable planetary systems that have large objects orbiting around moons? Or is the number of levels of orbit restricted to two? Thanks!
