Where on earth is closest to the moon?

Answer 1

The Moon orbits over the tropical areas, within about 28 degrees of latitude north or south. The point on the Earth which is absolutely the CLOSEST to the Moon would be the point when the Moon reaches its "perigee". But that point moves as the Moon orbits the Earth.

Answer 2

The point on Earth closest to the moon varies depending on the moon's position in its orbit. However, the point on Earth closest to the moon on average is in the Kiritimati Island in the Pacific Ocean.
