The Moon is the earth's only natural satalite, it is over 384,400 kilometers away or 238,900 miles away!, it's built up of mostly iron, it's surface is also possibly made of olivine and pyroxene, which are made up of magnesium, iron, silicon, and oxygen!!, the moon got its name from the latin word luna which means the word luna! it also shares the same name as other moons because people didn't know there was other moons until Galileo Galilei discovered four moons orbiting Jupiter in 1610!!!!
