How to name constellations in astronomy

China people have very special names. In ancient times, people numbered the stars from north to south and from east to west according to the constellations of China, such as Soapy and Soapy. But it is rarely used now. Only some brighter stars continue to use China's ancient names, such as Sirius and Vega. Some people have named brighter stars since ancient times, and they are still in use today. Stars discovered after other telescopes are numbered by constellations (much like China). There are 88 constellations in the whole day, which are cut into 88 regions. The brightest star in each region is α, followed by β and β. As for the following {inventor}, it should be {discoverer}. Comets and asteroids are named by discoverers, but other stars are not.

Does the star have a name? How is it named?

There are countless stars in the celestial sphere. In order to facilitate research and observation, people divide the starry sky into several regions, and each region is a constellation. Just as the province is divided into many counties and cities, each constellation is given the names of people, animals or objects in fairy tales. Western constellations first began in Babylonian times. In Ptolemy in the second century, the whole day was divided into 48 constellations, and then about 40 constellations were added, but the constellations were constantly changing and supplementing. 1930, the international astronomical society announced that the whole day would be divided into 88 constellations and their boundaries, including 28 in the north, 0/2 in the ecliptic/kloc, and 48 in the south. In ancient China, it was divided into stars and astrologers. Among them, the more important ones are Three Walls and Twenty-eight Nights. These three walls mean that the sky around the North Pole and overhead is divided into three areas, namely, Wei Zi Wall, Taiwei Wall and Shi Tian Wall, while the sky around the ecliptic and celestial equator is divided into four elephants. Among the four elephants, each elephant is subdivided into seven areas, collectively called 28 nights. These are the unique names of constellations in China.

There are countless bright stars in the night sky. In order to distinguish them, all the ancient nationalities named the stars. For example, the stars in the Three Walls and Twenty-eight Nights in ancient China were all named after emperors, officials, figures, vessels, animals and plants, such as the emperor, Jiuqing, Zhinv, Guansuo and Guagua. In the west, Babylonians first named the stars, and later Arabs and Greeks added them one after another. Today, about 200 stars have their own names, such as Sirius and Vega.

In the famous star map Uranometra published by Bayer Company in Germany in 1603, the stars are marked according to their brightness in the constellation, which is arranged in the order of 24 letters in Greece, and the name of the constellation to which the stars belong is added after the letters, such as α Orionis. After the Greek letters were used up, Latin letters (A, B, C ... and A, B, C) were used. In view of the fact that there are too many stars in the constellation and there are not enough letters, Flamsteed of the Royal Observatory uses numbers, such as 32 Leo. The order of numbers is arranged from the east to the west of the constellation, so that all stars can have names.
