As a result, although the Moon is moving to the east relative to the stars, the much faster westward motion of the sky is carrying it to the west, so despite its eastward motion relative to the center of the Earth, it rises in the east and sets in the west, just like any other celestial body.his means that from night to night the Moon moves a little more than one hand-width to the East (the direction of its motion around the Earth) relative to the stars, and from hour to hour it moves about one diameter to the East, among the stars. An approximate representation of the motion of the Moon around the Earth.
Not to be confused with Lunar orbit (the orbit of an object around the Moon). The Moon orbits Earth in the prograde direction and completes one revolution in approximately 27.322 days (a sidereal month).Earth and the Moon orbit about their barycentre (common center of mass), which lies about 4600 km from Earth's center (about three quarters of the radius of Earth).On average, the Moon is at a distance of about 385000 km from Earth's center, which corresponds to about 60 Earth radii.With a mean orbital velocity of 1.023 km/s, the Moon moves relative to the stars each hour by an amount roughly equal to its angular diameter, or by about 0.5Â°.n average, the Moon is at a distance of about 385000 km from Earth's center, which corresponds to about 60 Earth radii. With a mean orbital velocity of 1.023 km/s, the Moon moves relative to the stars each hour by an amount roughly equal to its angular diameter, or by about 0.5Â°.
