Moon

The moon is earths satellete, The first human to go to space was Neil Armstrong in July 16th 1969 and the moon was formed about 4.5 billion years ago The giant-impact hypothesis, sometimes called the Big Splash, or the Theia Impact, suggests that Luna (the Moon) formed from the ejecta of a collision between the proto-Earth and a Mars-sized planetesimal, approximately 4.5 billion years ago, in the Hadean eon (about 20 to 100 million years after the Solar System coalesced). The colliding body is sometimes called Theia, from the name of the mythical Greek Titan who was the mother of Selene, the goddess of the Moon. Analysis of lunar rocks, published in a 2016 report, suggests that the impact may have been a direct hit, causing a thorough mixing of both parent bodies.

The giant-impact hypothesis is currently the favored scientific hypothesis for the formation of the Moon.
