“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.

      Except it’s still inside the sun, so depending on how big you view the center of the sun it could still be wrong.

        So if the point is inside the sun, do we not consider the sun as orbiting that point? I would think it is still orbiting a point.

        The sun isn’t orbiting itself, though, so to say it’s wrong is also wrong. The sun is orbiting a small point in space that is affected by the bodies around it. That the point is covered by the sun doesn’t change that.

      My thought exactly but isn’t the common center still inside the sun?

              Now we all orbit KidnappedByKitties mom.

                Get in line! It’s you, everyone and the rest of the universe!

                Orbiting…

                Slowly watching…

                Slowly descending towards the crushing abyss…

                Fast or slow, near or far, there is inevitably only Mother…

                And the complete annihilation of her touch

        The common centre is the galaxy they both orbit spiral around together.

        Then, the galaxy moves around some other point along with other galaxies.

        Then, a bunch of aliens are playing with marbles.

      Yeah, any 2 bodies actually orbit a common point in between themselves. In case of the Sun and Earth that point is probably still inside the Sun, not far from the center.

      I mean, yeah, but the bigger argument here is that due to the sheer mass of Jupiter, the centre of mass of our solar system is actually very so slightly outside of the sun
