Earth-Moon barycenter

Earth-Moon barycenter

The Earth-Moon barycenter (EMB), is the barycenter, or center of mass, of the Earth-Moon system of celestial bodies. It is the point about which the Earth and Earth's Moon orbit (as they travel around the sun). [ [ Archive of Astronomy Questions and Answers ] ]

The location of the EMB is on the line connecting the centres of the Earth and Moon, approximately 1710 km below the surface of the Earth.
