49 Aurigae is a single[8] star located 680[1] light years away from the Sun in the northern constellation of Auriga.[7] It is visible to the naked eye as a dim, white-hued star with an apparent visual magnitude of 5.26.[2] The star is moving away from the Earth with a heliocentric radial velocity of +17 km/s, having come to within Script error: No such module "convert". some 5.5 million years ago.[2] It is positioned near the ecliptic and thus is subject to lunar occultations.[9][10]
This object is an A-type main-sequence star with a stellar classification of A0 Vnn,[3] where the 'n' notation indicates "nebulous" lines due to rapid rotation. It is spinning with a projected rotational velocity of 149 km/s.[6] This star has around 2.3[4] times the radius of the Sun and is radiating over three[2] times the Sun's luminosity from its photosphere at an effective temperature of 8,794 K.[5]
