The Moon travels around the Earth. The Moon travels around the Earth in a circle called an orbit. How long does it take the Moon to orbit the Earth? The Moon takes about 27 days (27 days, 7 hours, 43 minutes, 11.6 seconds) to go all the way around the Earth and return to its starting position. The Moon's orbit around the Earth is a slightly squashed circle called an ellipse.
Rating Newest Oldest. Best Answer: It depends on how you define orbit. If you define orbit to mean the time it takes the Moon to come back to the same point with respect to the Sun (new moon to new moon), that is a synodic month, which is 29.53059 days. If you define orbit to mean the time it takes the Moon to come back to the same point with respect to a fixed star, that is a sideral month, which is 27.32166 days.
