Weak countries have no diplomacy and the ultimate goal is to invade the moon.

Images of the Moon (20 photos) 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. 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 kilometers, which is 1 4 of the earth and 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 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 Moon surface is about 1 6 of the Earth's gravity

1. The moon, commonly known as the moon, also known as Taiyin and Xuantu in ancient times, is the only natural satellite of the earth and the fifth largest satellite in the solar system.

2. The diameter of the Moon is one-quarter of that of the Earth, and the mass is 1 81 of the Earth. The acceleration due to gravity is 1 6 of the Earth's surface

3. The moon rotates while revolving around the earth, and the period day is exactly a sidereal month, so we can't see the far side of the moon.

4. Lunar eclipse: refers to the fact that when the moon passes behind the shadow of the earth, the sun's rays are blocked by the earth. Therefore, there may be a lunar eclipse around the 15th of the lunar calendar.

At this time, the Sun, Earth, and Moon happen to be (or almost) in the same straight line, so the light from the Sun to the Moon is obscured by the Earth.

Ahh

There are many, many questions and mysteries left by the moon, waiting for us to explore further!

The Moon, the Earth's only natural satellite, is the closest celestial body to us, with an average distance of about 384401 kilometers from the Earth. Its average diameter is about 3476 km, which is slightly larger than 1 4 of the Earth's diameter. The surface area of the moon is 38 million square kilometers, which is not as large as our Asian area.

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

The moon itself does not emit light, only reflects sunlight. Its brightness varies with the angular distance between the Sun and the Moon and the distance between the Earth and the Moon. The brightness at the full moon averages so on.

The surface of the Moon is a desert of plains, peaks and valleys. There are also many craters formed as a result of space objects hitting the surface of the moon at high speed. There is no air on the moon for humans to breathe, but there may be water for drinking.

Ice was recently discovered at the bottom of a deep crater on the dark side of the Moon. Scientists believe the ice may have been brought by a comet that collided with the moon. The comet's ice did not melt because the temperature on the shady side of the moon was very low.

China's landing on the moon Academician Long Lehao, deputy chief designer of China's lunar exploration project, revealed in an interview with Hong Kong ** a few days ago that China plans to complete a manned lunar exploration flight in 2024, which includes walking on the surface of the moon. According to the **, this news is a sign of China's ambitions in space exploration. The moon landing program comes on the heels of China's first manned space flight in 2003 and the successful multi-day astronaut flight in 2004.

The two-ton Chang'e satellite, named after ancient Chinese mythology, will be launched into lunar orbit next spring. Academician Ouyang Ziyuan, the chief scientist of the lunar exploration project, said this in an interview a few days ago. Chang'e-1 will be in lunar orbit for at least a year, recording images of the lunar surface, studying the moon's electromagnetic waves, documenting the distribution of available metallic elements, and the thickness of the moon's surface soil.

In an interview with Hong Kong's Wen Wei Po on Monday, Long said that before sending people to walk on the lunar surface, we will first send a robot to the lunar surface in 2017 and let it collect a sample of the lunar surface when it returns. In 2020, the spacecraft landed on the surface of the moon, collected rock samples, and conducted other experiments, which also laid the groundwork for human landing. According to Ouyang Ziyuan's interview with "Shanghai**", scientists have overcome four major design obstacles in the plan to fly around the moon, which are mainly related to technical problems in the control of the vehicle and the connection with the ground.
