How many constellations is the whole sky divided into
88
Astronomers divide the stars in the whole sky into 88 constellations by region. 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 Ziweiyuan, Taiweiyuan and Shi Tian Wall, while the celestial sphere around the ecliptic and 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.
