I never really heard about such occurencies and now asked my self if this could be possible.
So could there be systems with a star (or black hole) that is so heavy that other less heavy stars are orbiting it?
I could imagine 2 things that would both be a no.
First, this isn't possible for so heavy objects they would just be affect each other and not one beeing a stable center.
Or the second option is this wouldn't be possible withing a galaxy since this would just form a galaxy.
So except the 2 named scenarios, could this happen within a galaxy or would this jsut form something diferent?
