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.

The Moon is Earth 's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period (lunar day) at 29.5 Earth days, causing the same side of the Moon to always ...
Internal structure of the Moon. Moon's internal structure. Olivine basalt collected by Apollo 15. Thermal state of the Moon at age 100 Ma. [1] Having a mean density of 3,346.4 kg/m 3, [2] the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core. This structure is believed to have resulted ...
Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data. . Six locations were sampled directly during the crewed Apollo program landings from 1969 to 1972, which returned 382 kilograms (842 lb) of lunar rock and lunar soil to Earth [8] In addition, three robotic Soviet Luna ...
Exploration of the Moon. The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made a deliberate impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of lunar exploration had been observations from Earth.
Made a closest approach of 1,950 kilometres (1,210 mi) on 18 September, and circled the Moon before returning to Earth. Landed in the Indian Ocean on 21 September at 16:08 UTC, becoming the first Lunar spacecraft to be recovered successfully and carried the first Earth life to travel to and around the Moon.

Luna 1. Luna 1, also known as Mechta (Russian: Мечта [mʲɪt͡ɕˈta], lit.: Dream), E-1 No.4 and First Lunar Rover, [4] was the first spacecraft to reach the vicinity of Earth's Moon, the first spacecraft to leave Earth's orbit, and the first to be placed in heliocentric orbit. Intended as a Moon impactor, Luna 1 was launched as part of ...
A Trip to the Moon (French: Le voyage dans la lune) [a] is a 1902 French science-fiction adventure trick film written, directed and produced by Georges Méliès.Inspired by Jules Verne's 1865 novel From the Earth to the Moon and its 1870 sequel Around the Moon, the film follows a group of astronomers who travel to the Moon in a cannon-propelled capsule, explore the Moon's surface, escape from ...
