What does the far side of the moon look like, what is the far side of the moon

What exactly is on the far side of the Moon?

The terrain on the back side of the sphere is dominated by a large number of undulating impact craters, such as the second largest in the solar system, the South Pole-Aitken Basin in Antarctica, and relatively few in the flat lunar sea.

The far side of the moon is the side of the moon that is always facing away from the earth, and it is never fully visible from the earth (18% of the back side can be seen because of the libra motion), so it is called the far side of the moon.

The first image of the far side of the moon was taken by the Soviet Union's Luna-3 spacecraft in 1959, and humans did not see the far side of the moon directly with their eyes until the Apollo 8 mission orbited the moon in 1968. The terrain on the far side of the Moon is dominated by a large number of undulating impact craters, such as the second largest crater in the solar system, the South Pole-Aitken Basin at the South Pole, and relatively few in the flat lunar sea. On the far side of the Moon, radio interference from the Earth will be obscured, so some scholars have suggested that a high-power radio telescope should be placed on the far side of the Moon.

The characteristics of the two hemispheres are markedly different, with many huge lunar seas on the front (this is a cognitive error of early astronomers who thought that these plains had water, so they called them seas); On the other side, there was a lot of craters, only a few, and about the area was covered by the sea, compared to the sea on the front. The most likely solution to this discrepancy is that the generation of heat is concentrated in the frontal hemisphere, as in the geochemical maps of ray spectroscopy from lunar explorers, which have been confirmed. Other factors, such as surface uplift and the thickness of the earth's crust, also affect the basalt eruptions, but none of this explains why the Antarctica-Aitoken Basin (with the lowest and thin crust on the Moon) does not have as much volcanic activity as the storm ocean in front.

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 the early astronomer Takaga observed the moon, he thought that the dark areas were covered by seawater, so he 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 has always been a world of unforeseen knowledge.

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.
