  The moon measures about 2160 miles (3476 km) across. The distance is about one fourth the diameter of the Earth, and 400 times smaller than that of the sun.
While our two celestial bodies remain locked in orbit, the moon is slowly â very slowly â inching away from Earth, at a rate of about 3.8 cm a year. Right now the moon is more than 238,000 miles from Earth, but when it formed, it was just 14,000 miles away. How do scientists know? The moon's distance is measured by bouncing laser beams off reflectors on the moon's surface that astronauts from the Apollo missions left behind.
