  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.
The diameter of the moon is about 3500 kilometers (edit: equatorial circumference â 11000km), smaller than we imagine: A well trained marathon walker can cover almost 50 kilometers per day.
