Moon
The Moon is an astronomical body that orbits planet Earth and is Earth's only permanent natural satellite . It is the fifth-largest natural satellite in the Solar System , and the largest among planetary satellites relative to the size of the planet that it orbits (its primary ). The Moon is after Jupiter 's satellite Io the second- densest satellite in the Solar System among those whose densities are known.

The Moon ( Latin : Luna ) is Earth 's only natural satellite . [e] [f] [8] Although not the largest natural satellite in the Solar System , it is, among the satellites of major planets, the largest relative to the size of the object it orbits (its primary ). [g] [h] It is the second- densest satellite among those whose densities are known (after Jupiter 's satellite Io ). |

The Moon is the only natural satellite of the Earth [d] [7] and the fifth largest moon in the Solar System . It is the largest natural satellite of a planet in the Solar System relative to the size of its primary , [e] having 27% the diameter and 60% the density of Earth, resulting in 1 ⁄ 81 its mass . Among satellites with known densities, the Moon is the second densest, after Io , a satellite of Jupiter. |

The Moon is a natural satellite of the Earth , [nb 4] [6] and the fifth largest satellite in the Solar System . It is the largest natural satellite of a planet in the Solar System relative to the size of its primary , having a quarter the diameter of Earth and 1 ⁄ 81 its mass . [nb 5] The Moon is the second densest satellite after Io , a satellite of Jupiter. It is in synchronous rotation with Earth, always showing the same face; the near side is marked with dark volcanic maria among the bright ancient crustal highlands and prominent impact craters . It is the brightest object in the sky after the Sun , although its surface is actually very dark, with a similar reflectance to coal. Its prominence in the sky and its regular cycle of phases have, since ancient times, made the Moon an important cultural influence on language , calendars , art and mythology . The Moon's gravitational influence produces the ocean tides and the minute lengthening of the day. The Moon's current orbital distance, about thirty times the diameter of the Earth, causes it to appear almost the same size in the sky as the Sun, allowing it to cover the Sun nearly precisely in total solar eclipses . |

The Moon is Earth's only natural satellite and the fifth largest satellite in the Solar System . The average centre-to-centre distance from the Earth to the Moon is 384,403 kilometres (238,857 mi), about thirty times the diameter of the Earth. The common centre of mass of the system (the barycentre ) is located at about 1,700 kilometres (1,100 mi)—a quarter the Earth's radius —beneath the surface of the Earth. The Moon makes a complete orbit around the Earth every 27.3 days [nb 4] (the orbital period ), and the periodic variations in the geometry of the Earth–Moon– Sun system are responsible for the phases of the Moon , which repeat every 29.5 days [nb 5] (the synodic period ). |

The Moon ( Latin : Luna ) is Earth 's only natural satellite , and is the fifth largest one in the Solar System . The average centre-to-centre distance from the Earth to the Moon is 384,403 km, which is about thirty times the diameter of the Earth. The Moon has a diameter of 3,474 km [8] —slightly more than a quarter that of the Earth and slightly smaller than the east–west distance across the United States. This means that the volume of the Moon is about 2 percent that of Earth. The gravitational pull at its surface is about 17 percent of the Earth's. The Moon makes a complete orbit around the Earth every 27.3 days, and the periodic variations in the geometry of the Earth–Moon– Sun system are responsible for the lunar phases that repeat every 29.5 days. |

The Moon is Earth 's only natural satellite . It has no formal English name other than "the Moon", although it is occasionally called Luna ( Latin : moon ) to distinguish it from the generic term " moon " (referring to any of the various natural satellites of other planets). Its symbol is a crescent (☽). The related adjective for the Moon is lunar (from the Latin root), but this is not found in combination with words using the prefix seleno- or suffix -selene (from the Greek deity Selene ). |
