In fact, as the Moon travels around the Earth in a counter-clockwise orbit every 27.5 days, it also completes one full rotation on its axis â also moving in a counter-clockwise direction.
The moon orbits quite fast: it moves about 0.5 degrees per hour in the sky. In 24 hours it moves 13 degrees. The moon's observed motion eastward results from its physical motion of the moon along its orbit around the Earth. The distance from the Earth to the moon is about 60 times the Earth's radius, about 384,000 km. The moon orbits counterclockwise around the Earth. Orbit is slightly elliptical and distance from Earth varies 6 %. Period of the orbit is about 27.3 days. This is called the SIDERIAL PERIOD or SIDEREAL MONTH. This is measured with respect to the background stars: the moon takes 1 sidereal period to cycle around once.
