<P> The Moon orbits Earth in the prograde direction and completes one revolution relative to the stars in about 27.32 days ( a sidereal month ) and one revolution relative to the Sun in about 29.53 days ( a synodic month ) . Earth and the Moon orbit about their barycenter ( common center of mass ) , which lies about 4,600 km ( 2,900 mi ) from Earth 's center ( about 3 / 4 of the radius of Earth ) . On average , the distance to the Moon is about 385,000 km ( 239,000 mi ) from Earth 's center , which corresponds to about 60 Earth radii . </P>
