Answer 2

A constellation is an area of the celestial sphere as defined by the International Astronomical Union (IAU) in the early 20th century.

Constellations are typically grouped around asterisms, patterns formed by prominent, relatively bright stars that appear to be close to each other in the night sky.

These star patterns themselves are often mistakenly called constellations, whether they are famous asterisms like Orion’s Belt, the Big Dipper or the Southern Cross, or less familiar patterns formed by stars visible to the naked eye and belonging to one of the 88 constellations.
