The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years. If you set a single green pea next to a U. The Moon is Earth's only natural satellite. It goes around the Earth at a distance of about , miles , kilometers. The Earth and Moon are tidally locked. Their rotations are so in sync we only see one side of the Moon. Humans didn't see the lunar far side until a Soviet spacecraft flew past in The Moon has a solid, rocky surface cratered and pitted from impacts by asteroids, meteorites, and comets. The Moon has a very thin and tenuous atmosphere called an exosphere. It is not breathable. More than robotic spacecraft have been launched to explore the Moon. It is the only celestial body beyond Earth — so far — visited by human beings. The Moon's weak atmosphere and its lack of liquid water cannot support life as we know it. Apollo astronauts brought back a total of pounds kilograms of lunar rocks and soil to Earth.
We always see the same side of the Moon. The Moon has a solid, rocky surface. There's no rain or wind, but there is weather. Earth's Moon is the brightest and largest object in our night sky. The Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years. The Moon was likely formed after a Mars-sized body collided with Earth several billion years ago. Earth's only natural satellite is simply called "the Moon" because people didn't know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in

Retrieved 16 November Ocean tides are the most widely experienced result of this, but tidal forces also considerably affect other mechanics of Earth, as well as the Moon and their system.

The Moon is Earth 's only natural satellite. It orbits at an average distance of , km , mi , about 30 times Earth's diameter. The Moon always presents the same side to Earth, because gravitational pull has locked its rotation to the planet. This results in the lunar day of The Moon's gravitational pull — and to a lesser extent the Sun 's — are the main drivers of the tides. The Moon is in geophysical terms a planetary-mass object or satellite planet. It has a mass that amounts to 1. The body of the Moon is differentiated and terrestrial , with no significant hydrosphere , atmosphere , or magnetic field. It formed 4. The lunar surface is covered in lunar dust and marked by mountains , impact craters , their ejecta , ray-like streaks and, mostly on the near side of the Moon, by dark maria "seas" , which are plains of cooled magma. These maria were formed when molten lava flowed into ancient impact basins. The Moon is, beside when passing through Earth's shadow during a lunar eclipse , always illuminated by the Sun, but from Earth the visible illumination shifts during its orbit, producing the lunar phases. This is mainly due to its large angular diameter , while the reflectance of the lunar surface is comparable to that of asphalt. The apparent size is nearly the same as that of the Sun, allowing it to cover the Sun almost completely during a total solar eclipse. For humans the Moon has been an important source of inspiration and knowledge, having been crucial to cosmography , mythology, religion , art, time keeping , natural science , and spaceflight. On September 13, , the first human-made object to reach an extraterrestrial body arrived on the Moon, the Soviet Union 's Luna 2 impactor. In , the Moon became the first extraterrestrial body where soft landings and orbital insertions were achieved. On July 20, , humans for the first time landed on the Moon and any extraterrestrial body, at Mare Tranquillitatis with the lander Eagle of the United States ' Apollo 11 mission.
The Greek goddess of the wilderness and the hunt, Artemisequated with the Roman Dianaone of whose symbols was the Moon and who was Moon regarded as the goddess of the Moon, was also called Cynthiafrom her legendary birthplace on Mount Cynthus. Archived from the original on 18 July South China Morning Post. Moon simulations show that most of the Moon derived from the impactor, Moon, rather than the proto-Earth, Moon. Galileo Project. Archived from the original on 9 November Computer simulations of giant impacts have produced results that are consistent with the mass of the lunar core and the angular momentum of the Earth—Moon system.

They are Moon in twardy szampon with enhanced surface magnetic fields and many are located at the antipodal point of major impacts.

Delays in the tidal peaks of both ocean and solid-body tides cause torque in Moon to the Earth's rotation. Missions at Moon far side of the Moon or the lunar north and south polar regions need spacecraft with special orbits, Moon as the Queqiao relay satellite or the planned first extraterrestrial space station, the Lunar Gateway.

Crystallization of this magma ocean would have created a mafic mantle from the precipitation and sinking of the minerals olivineMoon, clinopyroxeneand orthopyroxene ; after about three-quarters of the magma ocean had crystallized, lower-density plagioclase minerals could form and float into a crust atop.

Retrieved 22 August During the Middle AgesMoon the invention of the telescope, the Moon was increasingly recognised as a sphere, though many believed that it was "perfectly smooth", Moon. August The Moon originally rotated at a faster rate, but early in its history its rotation slowed and became tidally locked in this orientation as a result of frictional effects associated with tidal deformations caused by Earth. Although only lakier do włosów z brokatem hebe few multi-ring basins have been definitively dated, Moon, they are useful for assigning relative ages, Moon. Archived Moon the original on 21 April But since these flags lack the star, Moon, which along with the half-moon is to be found on Sassanid and Byzantine municipal coins, it may be regarded as an innovation of Mehmed. When exposed to solar radiation, water quickly decomposes through a process known as photodissociation and is lost to space. The apparent orientation of the Moon depends on its Moon in the sky and the hemisphere of the Earth from which it is being viewed. Hear Ye! Thomas Harriot had made, but not published such drawings a few months earlier, Moon.
