The Moon's heavily cratered far-side. The origin of the Moon is usually explained by a Mars-sized body striking the Earth, creating a debris ring that eventually collected into a single natural satellite, the Moon, but there are a number of variations on this giant-impact hypothesis, as well as alternative explanations, and research continues into how the Moon came to be formed.
Visiting the Moon with the Apollo missions in the late 1960s and early 1970s revolutionized our understanding of the Moon’s origins.

In this phase, the Moon is in the same part of the sky as the Sun and rises and sets with the Sun. Not only is the illuminated side facing away from the Earth, it’s also up during the day!
Moon - Formation, Craters, Orbit: With the rise of scientific inquiry in the Renaissance, investigators attempted to fit theories on the origin of the Moon to the available information, and the question of the Moon’s formation became a part of the attempt to explain the observed properties of the solar system (see Solar system: Origin of the solar system). At first the approach was largely ...
A Moon landing or lunar landing is the arrival of a spacecraft on the surface of the Moon, including both crewed and robotic missions. The first human-made object to touch the Moon was Luna 2 in 1959. [3] In 1969 Apollo 11 was the first crewed mission to land on the Moon. [4]
