constellation
Definition
Constellation is an area of the night sky that is defined by a group of stars that appear to be close together.
Constellations are not physical objects but are simply the way that our brains group together stars that are relatively close together in space.
The constellations are named after animals, people, and objects, and they have been used for centuries to help people find their way around the night sky.
The International Astronomical Union (IAU) is the organisation that is responsible for defining the boundaries of the constellations.

A constellation is a group of stars that form a recognisable pattern or shape in the night sky. Astronomers use constellations as a way to identify and locate celestial objects.
