The Moon is exceptionally large relative to Earth: a quarter its diameter and 1/81 its mass. It is the largest moon in the Solar System relative to the size of its planet, though Charon is larger relative to the dwarf planet Pluto, at 1/9 Pluto's mass.
The Moon's orbit around Earth is not a perfect circle, but elliptical, with one side closer to Earth than the other. As a result of the Moon's elliptical orbit, the distance between the Moon and Earth varies throughout the month and the year. On average the distance is about 382,900 kilometers (238,000 miles). The point on the Moon's orbit closest to Earth is called the perigee and the point farthest away is the apogee.
