Does this mean even the sun orbits around that point?
- ah27182 7y agoYep. Thats the cool thing about the center of mass: its always the center of rotation for a set of moving bodies.
- pbhjpbhj 7y agoOf course the point isn't a point, the solar system is moving relative to the galactic centre, which is moving relative to other galaxies. And space itself is changing. So as, pointed out elsewhere, we choose our points of reference and they're pretty arbitrary when you consider the whole Universe.
