It is wrong for people to see the back of the moon on the earth. Because the rotation period of the moon is the same as that of period of revolution, only one side of the moon is always facing the earth, and only the side facing the earth can be seen on the earth, and the back of the moon can never be seen.
Because the rotation and revolution of the moon are exactly the same, we can only see one side of the moon from the earth, not half the moon. In fact, we can see 68% of the moon at most.
In recent decades, due to the development of space technology, people take pictures on the back of the moon by spacecraft and send them back to Earth, which makes people know something about the back of the moon. Recently, China's lunar probe landed on the back of the moon, which is the first time in human history.
The moon is the planet of the earth;
The moon, the name of the celestial body, is called the moon as seen by the naked eye. In ancient times, it was also called Taiyin, Xuantu, Chanjuan and Pan Yu. It is a satellite of the earth and the fifth largest satellite in the solar system. The diameter of the moon is about a quarter of that of the earth, and its mass is about one-eighty-first of that of the earth.
The moon is the largest satellite 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 380,000 kilometers, which is about 30 times the diameter of the earth.
