Ask for information about the Moon Culture 20, about the Moon Introduction to the Moon

1. The moon, the name of the celestial body, is called the moon as seen by the naked eye of human beings, and is also known as Taiyin, Xuantu, Chanjuan, and Yupan in ancient China, which is a satellite of the earth and the fifth largest satellite in the solar system. The Moon is about a quarter of the diameter of the Earth and about one-eighty-one times the mass of the Earth. Its surface is covered with craters formed by the impact of small celestial bodies.

The average distance between the Moon and the Earth is about 10,000 kilometers, about 30 times the diameter of the Earth.

2. The Moon is the only natural satellite of the Earth, which may have been formed about 4.5 billion years ago, and shortly after the formation of the Earth, there are several hypotheses about its origin, and the claim supported by more factual evidence is that it was formed by the debris produced by a huge impact between the Earth and a Mars-sized celestial body - "Theia", and gathered in the outer periphery of the Earth to form the "Great Collision Origin Theory".

The moon is also known as the sun yin, commonly known as the moon. It is the only natural satellite of the Earth, the closest celestial body to the Earth, and the most thoroughly studied celestial body. The only celestial body that humans have ever visited in person is the Moon.

The Moon is the most obvious example of a natural satellite. In the solar system, except for Mercury and Venus, all other planets have natural satellites. The age of the Moon is about 4.6 billion years.

The Moon has a layered structure such as a shell, mantle, and nucleus. The average thickness of the outermost lunar crust is about 60-65 km. Below the lunar crust to a depth of 1,000 km is the lunar mantle, which occupies most of the moon's volume.

Underneath the mantle is the lunar core, which is about 1000 degrees warm and most likely molten. The diameter of the Moon is about 3476 km, which is 3 11 of the Earth and 1 400 of the Sun. The volume of the Moon is only 1 49 of the Earth, and the mass is about 735 billion tons, which is equivalent to about 1 81 of the Earth's mass, and the gravity of the lunar surface is almost 1 6 of the Earth's gravity.

There are dark parts and bright areas on the surface of the Moon. When early astronomers looked at the moon, they thought that the dark areas were covered by seawater, so they called them "seas". The famous ones are the sea of clouds, the wet sea, the still sea, etc.

The bright part is the mountains, which are dotted with craters. Located near Antarctica, the Bailey crater is 295 kilometers in diameter and can fit the entire island of Hainan. The deepest mountain is Newton's crater, which is 8,788 meters deep.

In addition to craters, there are also ordinary mountains on the lunar surface. Mountains and deep valleys are stacked on top of each other, creating a unique scenery.

The far side of the moon map The front of the moon is always facing the Earth, and the reason for this is the result of the long-term action of the tides. On the other hand, the far side of the Moon is mostly invisible from the Earth, except in the area near the edge of the Moon's surface which 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.

Since ancient times, people have endowed the moon with various cultural significance, and many ethnic groups have myths and legends about the moon, articles and poems, couplets, riddles, **, paintings, as well as folk customs and scenic spots related to the moon.

Now, there are many myths and legends related to the moon, which were first contained in ancient books such as "Classic of Mountains and Seas", "Chu Ci" and "Huainanzi", which have a lot of reference value for China's future research on the moon. There have been stories among the people such as Chang'e running to the moon and Zhu Yuanzhang's anti-Yuan uprising.

The moon can be said to be the representative of art, and it is said in Qu Yuan's "Chu Ci Tianwen": What is the virtue of night light, and death is childbearing? What is it, and Gu Rabbit is in the belly?

Translated into modern times, the question is: What are the characteristics of the moon, which dies and grows again? What are the benefits of raising a rabbit in your arms?

The Moon is a spherical body that revolves around the Earth and is also a natural satellite of the Earth. The Moon is the fifth largest moon in the solar system, with an average radius of about one kilometer, which is twice the radius of the Earth. The rotation of the Moon is equal to the period of revolution, so the Moon always faces the Earth on the same side.

The front side of the moon is dotted with huge impact craters filled with basalt lava flows ejected from dark volcanoes, forming a vast plain called the "Moon Sea", in fact, there is not a drop of water in the "Moon Sea".

The moon is the brightest object in the sky other than the sun, and although it appears very bright white, its surface is actually very dark and its reflectivity is only slightly higher than that of old asphalt.

Because the moon is very conspicuous in the sky, coupled with the regular changes in the phases of the moon, it has had a significant impact on human culture such as myths and legends, religious beliefs, philosophical thoughts, calendar compilation, literature and art, and customs and traditions since ancient times.
