The Moon's Orbit and Rotation. It takes the Moon 27.322 days to go around the Earth once. Because of this motion, the Moon appears to move about 13 against the stars each day, or about one-half degree per hour.
Tagged as. The earth rotates on its axis and one full rotation takes 24 hours to complete. Weâd be very surprised if you didnât already know that, but what you may not know is that the speed of the earthâs rotation can change from day to day and year to year. So a true solar day is not exactly 24 hours, but the variations are a matter of seconds.
