Does the Moon revolve around the Earth, or do they spin around each other as they revolve around the sun?

Answer 1

The Earth-Moon Barycenter, or EMB, is the center of mass of the Earth and Moon. It is located approximately 1,700 km below the surface of the Earth and is the center of their orbit.

Similar to this, the solar system consists of a barycenter situated above the surface of the Sun, around which the Sun, along with all other planets and bodies, orbits.

The solar system barycenter is orbited by the Earth-Moon barycenter.
