41 Aurigae is a binary star[10] system located around 310–316 light years away from the Sun in the northern constellation of Auriga. It is visible to the naked eye as a dim, white-hued star with a combined apparent visual magnitude of 5.83.[10] This system is moving further from the Earth with a heliocentric radial velocity of 31 km/s.[11] It is a probable member of the Hyades Supercluster.[12]

As of 2012, the pair had an angular separation of Template:Val along a position angle of 357.7°.[13] The primary component is an A-type main-sequence star with a stellar classification of A2Va+[4] and a visual magnitude of 6.15.[2] The magnitude 6.84[2] secondary companion is a possible Am star[14] with a stellar classification of kA5hA5mF0(IV-V),[4] showing the calcium K line and hydrogen lines of an A5 star and the metal lines of an F0 star.
