Moon

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 In Latin, the Moon was called Luna, which is the main adjective for all things Moon-related: lunar. Why can I see the Moon during the day? And other frequently asked questions about our Moon. When the full moon is a little bit closer to us than usual, it appears especially large and bright in the sky.

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.

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.
