Constellation

A constellation is any one of the 88 areas into which the sky — or the celestial sphere — is divided. The term is also traditionally and less formally used to denote a group of stars visibly related to each other in a particular configuration or pattern.

Some well-known constellations contain striking and familiar patterns of bright stars. Examples are Orion (containing a figure of a hunter), Leo (containing bright stars outlining the form of a lion), Scorpius (a scorpion), and Crux (a cross).
