It seems to me that something that's a couple of lightyears out can't have any sort of stable orbit. I suppose that an Oort cloud essentially merges with an adjacent star's so there's no hard definition.
- lumost 5y agoAt the point of merger with neighboring stars it’s likely that circular orbits are unstable. Judging by our own solar system it’s likely that the distance at which circular orbits are stable is a question of relative mass, and time.
