The moon orbits the earth in a little under 28 earth days. It travels at almost 2,290 miles per hour. Coincidentally, the moon's rotation period is also a little under 28 days, meaning the same face points toward the earth during its entire orbit.
Best Answer: It takes 27.3 days for the moon to encircle Earth, but 29.5 days for it to return to the same spot in the sky relative to the sun [back to the same moon phase].he moon's phases take 29.5 days to complete one cycle, but that is made longer because of the Earth's orbit of the Sun. The real time it take to make one orbit of the Earth is 27.3 days. Kyle M Â· 7 years ago.
