Auriga (constellation) horizon. A large constellation, with an area of 657 square degrees, it is half the size of the largest constellation, Hydra. Its brightest star, Capella, is an unusual multiple star system among the brightest stars in the night sky. Beta Aurigae is an interesting variable star in the constellation; Epsilon Aurigae, a nearby eclipsing binary with an unusually long period, has been studied intensively.

In addition, it has one prominent nebula, the
