What are Some Prominent Features of the Moon?

The moon , the name of the celestial body, is called the moon when seen by human eyes, and it is also called the Taiyin , Xuantu , Yuanjuan , and Yupan . The moon is about a quarter in diameter and about one eighty-one in mass. The moon is the only satellite on Earth, and its surface is covered with craters formed by small celestial bodies. The average distance between the moon and the earth is about 384,400 kilometers, about 30 times the diameter of the earth.

The moon may have been formed about 4.5 billion years ago, and shortly after the formation of the Earth, there are several sources of its origin

There are dark parts and bright areas on the surface of the moon . The bright areas are highlands and the dark areas are low depressions such as plains or basins.

On May 16, 2019, the National Astronomical Observatory of the Chinese Academy of Sciences announced that a research team led by researcher Li Chunlai used Chang'e-4 exploration data to prove that the Antarctic-Aitken Basin on the back of the moon is dominated by olivine and low-calcite pyroxene Deep matter. The international academic journal Nature published the major discovery online. This discovery provides direct evidence for answering questions about the composition of the lunar mantle that have long plagued scholars at home and abroad, and will provide support for improving the model of lunar formation and evolution. Sources from the National Astronomical Observatory of the Chinese Academy of Sciences said that the Chang'e-4 probe achieved the first soft landing in-situ detection of the moon's back in human history, and the results of the research based on the detection data successfully revealed the material composition on the back of the moon, confirming that The correctness of the inference that the lunar mantle is rich in olivine has deepened human understanding of the formation and evolution of the moon. ^[1]
