Constellation refers to one of the indispensable components of astrology, and also refers to the combination of stars in the sky. Since ancient times, human beings have associated three or five stars with their mythical figures or artifacts, which are called "constellations".

Constellation is a means to determine the orientation of the sky in almost all civilizations and is widely used in the field of navigation. The division of constellations is completely artificial, and different civilizations have different divisions and names. Constellations have never had a unified and precise boundary.
