Hey, I was reading some info that touched on orbital mechanics. and according to that source..... "planets in a given system tend to orbit in similar planes." This doesn't say that orbiting in the same, or similar planes is a set in stone rule. I was just wondering if it is possible to have a star system where some or all of the planets orbit in different planes? think like a model of an atom where the nucleus is the star, and the elcectrons are the planets. And do we know of any such star systems in existence?
