As I have found, the major objects in space are orbiting around the center of gravity in a curved orbit that usually (more and more with time) matches the rotational plane of the central mass. So let's say a new planet would enter the solar system. Whatever direction it arrives from (most probably one that does not match the rotational plane of the Sun), first it will not orbit in the rotational plane of the Sun. But with time, it will converge to that rotational plane of the Sun. Questions:
- Why is that? Does rotation of the central mass of gravity modify the gravitational effects actively? (Does it rotate the gravity field) Please note that I am asking here if the spacetime curvature gets modified by the rotation of the center of mass or not, so does curved spacetime look a little bit 'flatter' along the plane of rotation? (and so 'diverting' everything into the plane of rotation)
- if the Sun would not be rotating, then the new planet that would arrive in the solar system would just keep orbiting in its own rotational plane (defined by what angle it came from)
- the effects of gravity cause curved spacetime even without rotation? Have we seen a large non-rotating object in space that caused gravitational affects on its surroundings?
