Who has information about the Moon velocity

The Moon is the most thoroughly studied celestial body, and 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 layer of the lunar crust is about 60-65 millimeters. 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 1 4 kilometers and about 1 400 of the earth and 1 400 of the sun, and the macro 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 Earth's mass, and the gravity of the surface of the Moon is about 1 6 of the Earth's gravity.

At present, the most widely accepted theory of the formation of the moon is: an invasion star the size of Mars collides with the earth, and its debris and the blasted crust are thrown into space to form a gas disk around the earth.

The moon, the name of the celestial body, is called the moon as seen by the naked eye, and in ancient times, it was also called Taiyin, Xuantu, Chanjuan, and Yupan, which is the 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. The Moon is the most massive moon known to Earth, and 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.

On May 16, 2019, the National Astronomical Observatories of the Chinese Academy of Sciences announced that a research team led by Li Chunlai, a researcher at the Chinese Academy of Sciences, used the Chang'e-4 probe data to prove the existence of deep materials dominated by olivine and low-calcium pyroxene in the South Pole-Aitken Basin on the far side of the Moon. The international academic journal Nature published this important discovery.

The Moon, the closest star to us, but it is not a star, a planet, but the only natural satellite that orbits the Earth. Of course, the moon has been known since prehistory. It is second only to the sun in the air.

Since the Moon orbits the Earth once a month, the angle between the Earth, the Moon, and the Sun is constantly changing; We call it a synodic month. The appearance of a continuous crescent moon takes days (709 hours) and varies as the lunar orbital period (measured by stars) varies as the Earth simultaneously revolves around the Sun.

The Moon has no atmosphere. But evidence from the Clementine spacecraft suggests that there may be solid water ice at the south pole of the moon, in a large circumference on the permanently dark side. This has now been confirmed by the Lunar Prospector spacecraft.

Apparently there is also ice in the North Pole of the Moon. Its surface has two main types of topography: huge craters with ancient plateaus and relatively smooth with a young moon sea.

The topography of the Lunar Sea (covering up to 16 of the Moon's surface) is carved out by hot lava ejected from volcanoes. Most of the surface is covered by a layer of dust and stone fragments from meteor impacts. For unknown reasons, the lunar sea topography is concentrated on the side close to Earth.

Most of the craters near the Earth, the volcanoes are named after famous scientists in history, and the ones on the back are mostly named after modern times.

The Moon was first visited by the Soviet spacecraft Luna 2 in 1959 on behalf of mankind, and it was also the first time that mankind explored a non-Earth planet. It is also the only planet where surface samples have been recovered. In the summer of 1994, the Moon was extensively mapped by the Clementine spacecraft.

The Lunar Prospector is now orbiting the Moon.

The gravitational field between the Earth and the Moon creates an interesting phenomenon. The most obvious is the tidal phenomenon. The gravitational pull of the Earth directly opposite the Moon is the greatest, and the opposite point is weaker.

The Earth, and especially the oceans, are not completely fixed, but extend slightly towards the Moon. If you look at the Earth's surface from a perspective angle, you will see two points of expansion on the Earth's surface, one facing the Moon and the other facing the other opposite.
