How many constellations are there in the universe?

1922, the General Assembly of the International Astronomical Union decided to divide the sky into 88 constellations, and their names basically followed the historical names. 1928, the international astronomical union officially announced the names of 88 constellations. These 88 constellations are divided into three celestial regions, 29 in the northern hemisphere and 47 in the southern hemisphere, near the ecliptic 12. There are nearly 6000 stars visible to the naked eye. Each constellation can be identified by the special distribution of bright stars in it. Now there are 88 constellations commonly used in the world.
