62 Aurigae is a star located 561 light years away from the Sun in the northern constellation of Auriga.[8] It is visible to the naked eye as a dim, orange-hued star with an apparent visual magnitude of 6.02.[1] This object is moving further from the Earth with a heliocentric radial velocity of +25 km/s.[2] It is an aging giant star with a stellar classification of K2 III,[3] having exhausted the supply of hydrogen at its core then expanded to 21 times the Sun's radius.[4] 62 Aurigae is radiating 176 times the luminosity of the Sun[5] from its swollen photosphere at an effective temperature of 4,419 K.[6]
