how long does it take for the moon to go around earth

The Moon’s trip around Earth depends on what you mean by “go around.” There are two main cycles to consider:

• Sidereal month: This is the time it takes the Moon to complete one full orbit around Earth relative to the stars. It’s about 27.3 days.

• Synodic month: This is the time it takes for the Moon to go through all its phases, from new moon back to new moon again. This cycle is slightly longer, at about 29.5 days, because both the Moon and Earth are orbiting the Sun at the same time.

So, depending on what you mean by “go around,” the answer is either 27.3 days or 29.5 days.
