Extended data:

In order to facilitate Taoist astrologers to recognize stars, people divide several regions with different sizes according to the natural distribution of stars in the sky, and each region is called a constellation. Connect the bright stars in the same constellation with lines to form various figures. In shape, they are similar to animals and utensils. There are nearly 6,000 stars visible to the naked eye, each of which can be classified into a unique constellation, and each constellation can be identified by the shape of a bright star.

Basically, dividing stars into constellations is a random process. Different civilizations have different constellations made up of different stars-although some constellations made up of more conspicuous stars are roughly the same in different civilizations, such as Orion and Scorpio. The International Astronomical Union divides the sky into 88 official constellations with precise boundaries, so that every star in the sky belongs to a specific constellation.

Most of these official constellations are based on the ancient Greek traditional constellations handed down from the Middle Ages. Constellation plays an important role in astronomy, and astrology also uses the image of the zodiac. However, if astrology does not use real scientific methods, it will generally be considered as pseudoscience.
