What is the circumference of the moon?

The equatorial circumference of the Earth's moon is approximately 6,783 miles or 10,917 kilometers. As a comparison, if the Earth were reduced to the size of a nickel, the moon would be the size of a pea.

The moon orbits the Earth at an average distance of 239,000 miles or 384,000 kilometers. It takes 27 days for the moon to make a complete cycle around the Earth, and its position in relation to the sun during this orbit is responsible for the different phases of the moon. As the moon orbits the Earth, it rotates on its axis at the same rate. This is the reason why the same face of the moon is always observed from the Earth.
