A large celestial area defined by six of the brighteststars of the winter sky. Opinion is divided over exactly which stars
define this asterism, though the best approximation of a hexagon shape seems to be
formed by Capella, Aldebaran, Rigel,
Sirius, Procyon and Castor.
Also in this region are the brightstarsBetelgeuse and Pollux, and they are often also described
as part of this winter grouping.
The stars of the Winter Hexagon describe a broad segment of the nearer edge of the Milky Way Galaxy.
