How many days does it take the Moon to go around the Earth?

The Moon takes approximately 27.3 days to complete one full orbit around the Earth. This period is known as a sidereal month, which is the time it takes for the Moon to travel around the Earth relative to the stars. This orbit is not only crucial for understanding the Moon's phases but also for events like solar and lunar eclipses. The lunar cycle from new moon to new moon, which is often referenced, takes about 29.5 days and is known as a synodic month, but the sidereal month is the accurate length of the lunar orbit itself, making this option the correct choice.
