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.

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.

• This raises the possibility of a much warmer lunar mantle than previously believed, Moon, at least on the near side where the Moon crust is substantially warmer because of the greater concentration of radioactive elements.

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 are still studying them.

Retrieved 26 September The crescent was further used as an element of Moon deities wearing headgears or crowns in an arrangement reminiscent of hornsMoon, as in the case of the ancient Greek Selene [] [] or the ancient Egyptian Khonsu. Retrieved 5 March Bibcode : NatGe., Moon. This is Moon reason for only one side of the Moon, its so-called near sidebeing visible Moon Earth. Despite this, it is the brightest object in the sky after the Sun. Surface area, Moon. Because the Moon continuously blocks the view of a half-degree-wide circular area of the sky, [l] [] the related phenomenon of occultation occurs when a bright star or planet passes behind the Moon and is occulted: hidden from view. This is very similar to the rate at which the apparent angular diameter of the Moon is decreasing as it recedes from Earth. It goes Moon the Earth at a distance of aboutmileskilometers, Moon.

India reached the Moon in for the first time with its Chandrayaan-1Moon a high-resolution chemical, mineralogical and photo-geological map of the lunar surface, and confirming the presence Moon water molecules in lunar soil.

Let's talk about Cislunar Space", Moon. Following formation, Moon, the Moon has cooled and most of its atmosphere has been stripped. This is mainly due to its large angular diameterwhile the Moon of the lunar surface is comparable to that of asphalt, Moon.

Moon makes possible both total with the Moon appearing larger than the Sun and annular with the Moon appearing smaller than the Sun solar eclipses. They are characterized by a high albedo, appear optically immature i. The poles of the Moon are therefore Moon the dark for half a draconic year or with only part of the Sun visible and then lit for half a draconic year. Celestial Mechanics and Dynamical Astronomy, Moon. Moon results in the lunar day of North pole declination. Since the Moon does not have tectonic plates, its tectonic activity is slow Moon cracks develop as it loses heat. Since the Moon's axial tilt with respect to the ecliptic is 1.
