Are constellations related to the stars in the sky?

Constellation is the total number of celestial bodies in an area projected on the celestial sphere. So such a constellation is not accurate inside/outside the Milky Way.

Constellation refers to the stars in the sky. In the three-dimensional universe, these stars are not actually related to each other, but their positions on the celestial sphere are similar. Since ancient times, people have been interested in the arrangement and shape of stars, and naturally linked some stars with similar positions to form constellations.

Constellations play an important role in astronomy; Astrology also uses images of the zodiac 12, but astronomers regard astrology as pseudoscience without using real scientific methods.

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.
