“Some people say light is waves, and some say it’s particles, so I bet light is some in-between thing that’s both wave and particle depending on how you look at it. Am I right?” “YES, BUT YOU SHOULDN’T BE!”

      No it’s not. The common center here is the center of our galaxy which both orbit. Even if the sun wobbles a miniscule bit there is no common orbit between them.

        it is possible for objects to orbit multiple objects at the same time. Add the moon to the system. The moon is orbiting the earth that is orbiting the sun that is orbiting the center of our galaxy. And yes each of them have a common center, just that it is very very close to the center of mass of the larger object in each case.

        For the moon the earth is the dominant gravitational force, for the earth it is the sun and for the sun it is the center of our galaxy

          for the sun it is the center of gravity.

          You mean the galactic center, which in turn orbits a point somewhere in the middle of our local galactic cluster.

        There’s a very famous smart man with zany hair and a big tongue that says your comment is wrong and it’s all relative to your frame of reference.

        No the common center is called a barycenter and it’s somewhere just outside the middle of the sun.
