Technically, the sun is pulled by the earth too so it’s sort of true.
I mean, yeah. That's the joke.
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
You mean the galactic center, which in turn orbits a point somewhere in the middle of our local galactic cluster.
