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 at 29.5 Earth days, causing the same side of the Moon to always face Earth.
[137] [138] The last attempt to define acceptable detailed rules for exploitation, ended in June 2018, after S. Neil Hosenball, who was the NASA General Counsel and chief US negotiator for the Moon Treaty, decided that negotiation of the mining rules in the Moon Treaty should be delayed until the feasibility of exploitation of lunar resources ...

The Moon is just large enough to cover the Sun completely (at times) so that a temporary night falls and the stars spring out. [...] The Sun's greater distance makes up for its greater size and the result is that the Moon and the Sun appear to be equal in size. [...] There is no astronomical reason why Moon and Sun should fit so well.
Photograph of the far side of the Moon, with Mare Orientale (center left) and the mare of the crater Apollo (top left) being visible, taken by Orion spacecraft during the Artemis 1 mission. The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the near side, because of synchronous rotation in the Moon's ...
This week, learn why a lunar time scale is needed before humans return to the moon, meet the faces of Scotland’s ancient past, spy “salty licorice” cats, and more.
Moon dust-contaminated items finally became available to the public in 2014, when the US government approved [35] the sale of private material owned, and collected, by astronauts. Since then, only one item has been produced for sale with genuine Moon dust collected after the item spent over 32 hours on the Moon.
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 ...
