constellation

(division of the celestial sphere)

A constellation is a set of stars in the sky which people have decided form a group, typically named after an image that people find it resembles, of a person, animal, or object. Examples: Orion, Sagittarius, and Ursa Major. For astronomy, a set of standardized constellations are now used to refer to portions of the sky, i.e., 88 divisions of the sky defined by the International Astronomical Union (IAU). Names of objects (especially those viewable without a telescope) often reference the constellations that contain them, such as traditional stellar designations (Bayer designations and Flamsteed designations). Galaxy names often use them as well, e.g., Andromeda and Triangulum. Some constellations, such as Orion are commonly used in the world of astronomy for containing prominent objects of study such as star-forming regions.
