Could someone explain how orbits are so flat? For example, why do most of the planets orbit on the same plane instead of randomly? Why are galaxies flat instead of spherical? Gravity forms matter into a ball (planets, stars, etc..) so why not orbits?
I may be wrong but I believe that they’re just displayed that way for comparison’s sake. It’s easier to gage relative distance between planets and their orbits if they’re displayed on the same plane
