1. The Moon is the most thoroughly studied celestial body. The second celestial body that humans have ever visited is the Moon. The age of the Moon is about 4.6 billion years.

The Moon, like the Earth, has a layered structure such as a shell, mantle, and core. The average thickness of the outermost lunar crust is about 60-65 km.

2. Below the lunar crust to a depth of 1,000 kilometers is the lunar mantle, which occupies most of the volume of the moon. Underneath the mantle is the lunar core, which is about 1000 degrees warm and most likely molten. The diameter of the moon is about one kilometer, about 1 4 of the earth, 1 400 of the sun, and the distance from the moon to the earth is equivalent to 1 400 of the distance from the earth to the sun, so the moon is as big as the sun from the earth.

The volume of the Moon is about 1 49 of the Earth, and the mass is about 735 billion tons, which is almost equivalent to about 1 81 of the mass of the Earth, and the gravity of the surface of the Moon is about 1 6 of the Earth's gravity.

4.6 billion years ago, the earth was in the process of gestation, and life on the earth was not born. The solar system is still in the chaotic solar nebula stage. Around the young sun, in the huge gas dust nebula, dust and massive rocks continue to condense, collide, and accrete, and some of the material in the nebula begins to form planets and satellite systems around the sun.

About 100 million years ago, Earth, the third largest planet closest to the Sun, was hit by an unprecedented catastrophe. A planet the size of Mars is approaching quickly, as the orbits of the two planets intersect, making a huge impact inevitable. If we can jump to the perspective of the Milky Way to see the impending collision, we first need to look at the Sun, which is located on the third inner side of the Milky Way, which is just one of the 100 billion stars in the Milky Way.

In this way, the impact of planets around the Sun is completely invisible from the view of the Milky Way. But with the solar system as a reference, this is an earth-shattering collision. The impact threw the mantle and crustal material of the two planets into nearby space, leaving a large number of planetary impact debris in the vicinity of the Earth when the remaining impact planets changed their orbits and left.

Over time, the material surrounding the Earth gradually coalesced and began to form a separate celestial body. 4.5 billion years later, humans appeared as part of life on a third planet close to the Sun. Time has long since healed the scars of the earth, and the moon formed by the collision has occupied the night sky again and again.

What does the Moon look like? How is it different from Earth? What kind of impact does it have on the planet?

And what kind of future will that accidental blow in the universe bring to mankind?

The topography of the moon mainly includes craters, lunar seas, lunar lands and mountains, lunar radial streaks, moon valleys, etc.

①.How far away is the Moon? ②.What is the mass of the MoonWhy is the surface of the moon always bumpy? Friends, take it!

Moon (astronomical symbol: ?Commonly known as the moon and Taiyin in ancient times, it is a solid-state satellite orbiting the earth and the closest celestial body to the earth (the average distance is 10,000 kilometers). It is closely related to the Earth and is about 4.6 billion years old.

1] The atmosphere on the Moon is extremely thin, the heat capacity and thermal conductivity of the lunar surface material are very low, and the temperature difference between day and night on the surface is very large.

The Moon, like the Earth, has a layered structure such as a shell, mantle, and core. The diameter is about 3476 kilometers, which is about 3 11 of the Earth. The Moon emits light by reflecting sunlight, and the phases of the Moon also change periodically due to the cyclical changes in the position of the Moon and the Earth, with the moon appearing, the last quarter, the New Moon, and the first quarter moon, which cycle once a month (the average period is days).

Due to the tidal locking of the Earth, the Moon rotates the same period as it does and always faces us on one side. The far side of the Moon is mostly invisible from the Earth, except in the area near the edge of the lunar surface that is visible in the middle due to the movement of the scales. In the days when there were no probes, the far side of the moon was an unknown world.

One of the great features of the far side of the Moon is that there are almost no fainter lunar features like the Lunar Sea. And when an artificial probe runs to the far side of the moon, it will not be able to communicate directly with Earth.

The Moon is the most thoroughly studied celestial body, and the second celestial body that people have ever visited is the Moon. [2] In 1969, Neil Armstrong and Buzz Aldrin became the first humans to land on the moon. In September 1969, the American spacecraft Apollo 11 returned to Earth.

1 There is ice at the poles of the Moon, 2 There is a lunar sea on the Moon, and 3 There are more craters on the back side of the Moon than on the front, proving that the Moon has a certain protective effect on the Earth.
