Aldebaran is by far the brightest, and therefore the Alpha, star of the constellation Taurus. Because of its location in the head of Taurus, it has historically been called the Bull's Eye. It is a binary star system, Aldebaran A being a orange-red giant star and Aldebaran B, a relatively distant, red dwarf companion. The ancient name, from Arabic, means "the Follower," as the star seems to follow the Pleiades, or Seven Sisters star cluster, across the sky. Aldebaran, 60 light years away, is positioned in front of the sprawling Hyades star cluster (in mythology, half-sisters to the Pleiades) that make the face of Taurus the Bull.
