How many constellations are officially recognized?

The correct answer is 88, as this is the number of constellations officially recognized by the International Astronomical Union (IAU). The IAU established these 88 constellations in 1922 as a way to categorize and standardize the various patterns of stars seen in the night sky across different cultures and regions. These constellations cover the entire celestial sphere and are used for purposes such as navigation and astronomy.

By recognizing 88 constellations, the IAU provides a uniform framework that astronomers and stargazers around the world can use to identify and refer to celestial regions. The selection was based on historical and cultural significance with many constellations drawing from ancient Greek, Roman, and other traditions while also incorporating newer constellations to fill in gaps, particularly in the Southern Hemisphere.
