Ban Cai Zhao Wen Ji Wang Zhaojun Li Qingzhao Which woman's name was used to name the space crater?

1987, the International Astronomical Union named the first batch of craters on Mercury, two of which were named after Cai Wenji, a famous poetess in ancient China, and Li Qingzhao. These are the only two women whose names have been used as craters in outer space in history.

Crater, which means "plate" in Greek. "Crater Mountain" usually refers to the pit with bowl-shaped pit structure. The surface of the moon is covered with large and small round pits, which are called "moon pits". Most of the craters are surrounded by craters above the surface of the moon. There are more craters on the back of the moon.

There is a sunken crater in the middle of the crater, surrounded by towering and upright rocks. The height of the crater is usually between 7 and 8 kilometers. Craters vary in size and diameter. Small craters are less than 10 km in diameter, and some are only the size of a football field. The diameter of this pit exceeds 100 km. The largest crater is Bailey crater near the South Pole of the Moon, with a diameter of 295 kilometers, which is a little smaller than that of Zhejiang Province in China. The total number of moon pits with a diameter greater than 1000m has reached more than 3,300. Among them, the large diameter exceeds 100 km, accounting for 7- 10% of the lunar surface.

Most craters are named after famous astronomers or other scholars. The nine craters on the back of the moon are named after astronomers and inventors from ancient and modern China.

name

The name crater was given by Galileo. Crater is the most remarkable landform feature on the moon. The moon is covered with overlapping craters, similar to those on the earth. There is a round flat land in the middle and a raised mountain ring on the periphery. The inner wall is steep and the outer slope is gentle.

When ancient astronomers named the mountains on the moon, they stipulated that the mountains on the moon should be named after the mountains on the earth, and the craters on the moon should be named after world-famous scientists and thinkers. This provision is still in use today. Such as Copernicus crater, Archimedes crater, Newton crater, Iba Valley crater, Cassini crater, etc. Among the craters on the back of the moon, eight are named after ancient astronomers in China: Shen Shi crater, Zhangheng crater, Zu Chongzhi crater, Guo Shoujing crater, Wan Hu crater, Yuzhe Zhang crater, Cai Lun crater and Bi Sheng crater.

There is a crater in front, named after Gao, a modern astronomer in China.
