How many constellations are there in the whole day by sector?

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, divided along the right latitude and right longitude of the celestial equator coordinate system, kept the traditional constellation names, specified their scientific names in Latin, and clearly formed their abbreviation symbols with three capital letters, which were used uniformly all over the world.

Constellation is a group of stars with similar positions in the sky projected onto the celestial sphere. Most modern constellations evolved from the traditional constellations of ancient Greece, and the International Astronomical Union accurately divided the whole day into 88 constellations. Among them, there are five Gong Ji constellations in the northern sky, Polaris 19, Zodiac 12, Zodiac 10 and Southern Sky 42.

More than half of these 88 constellations originated from the early civilizations of ancient Babylonians and Greeks, and the images and symbolic meanings of these constellations are closely related to the myths of ancient Greece.
