How many constellations does IAU divide the starry sky into?

1928, in order to meet the needs of astronomical research, the General Assembly of the International Astronomical Union held in Leiden, the Netherlands clearly divided the whole sky into 88 constellation areas.

CONSTELLATION, whose Latin name is Constellation, refers to the combination of a group of stars with similar positions projected on the celestial sphere. English is "Constellation", which means "constellation" and "constellation"; Constellations in astrology mean "signs", "signs" and "symbols".

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.
