How did the name of the moon come from?

Scientists began to name the moon from 1609, when Galileo observed the mountains and depressions of the moon with his own telescope. But they all have a strong personal color. For example, Galileo named the largest mountain range on the moon after his hometown Apennines. At the same time, due to the lack of communication and authority, some moon websites have multiple names, which brings a lot of confusion. It was not until the establishment of 19 19 International Astronomical Union that this mutual naming situation was changed. The International Astronomical Union (IAU) is an authoritative astronomical academic organization recognized by all countries in the world and has the right to name planets and satellites. After decades of development and revision, the International Astronomical Union has gradually worked out a set of naming procedures and rules for lunar geographical entities. ?

At present, there are 18 types of landforms defined on the moon, including craters, moon flows and mountains, and different landforms have different naming methods. For example, the craters of important landforms on the moon use the names of celebrities such as outstanding scientists and philosophers; The names of the landforms such as Yuexi, Yuehu and Yuehai are abstract Latin words. Among the lunar naming rules formulated by the International Astronomical Union, one is very special, and that is the landing site of the moon. There is no fixed name requirement for this landform, but the applicant is required to have the ability to send spacecraft to the moon. Since the first lunar probe landed on the moon in 1959, there are not many such place names.

It should be emphasized that the naming rules formulated by the International Astronomical Union exclude celebrities in some fields, including/kloc-political and religious figures in the 9th century and beyond, and writers. Many craters on the moon were named after writers such as Li Bai, Balzac and Hugo, but these craters were deleted because the naming rules did not allow them. In the naming list published in 2006, Li Bai Pit was changed to Hume Z Pit.
