62 Aurigae
62 Aurigae is a star located 559[1] light years away from the Sun in the northern constellation of Auriga.[5] It is visible to the naked eye as a dim, orange-hued star with an apparent visual magnitude of 6.02.[2] This object is moving further from the Earth with a heliocentric radial velocity of +25 km/s.[1] 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 22[1] times the Sun's radius. 62 Aurigae is radiating 167[1] times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,389 K.[1]
