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.
The moon's motion through our sky is similar to that of the sun, but different: 1  Like the sun, the moon rises in the east and sets in the west (with some exceptions for observers in earth's extreme northern and southern regions). 2  Like the sun, the moon doesn't move across our sky quite as fast as the stars do. Third, when the moon is in its crescent phase and the sky is sufficiently dark, you can sometimes make out the rest of the moon's dimly lit disk. 2  This tells us that the moon isn't really changing shape; part of it is merely much brighter than the rest.
