The average distance earth-moon from the Center to the Center is 384,403 km, about thirty times the diameter of Earth. The diameter of the Moon is 3474 km, slightly smaller than a quarter the diameter of the Earth. This means the volume of the Moon is only about 2 percent of the volume of the Earth's gravitational pull and on its surface about 17 percent than the pull of gravity upon Earth. The moon revolves around the Earth once every 27.3 days (perode orbit), and the periodic variations in the earth-moon-Sun is responsible for the occurrence of Moon phases repeat every day 29.5 (perode sinodik).
