63 Aurigae is a single[6] star located around 395[1] light years away from the Sun in the northern constellation of Auriga.[5] It is visible to the naked eye as a faint, orange-hued star with an apparent magnitude of 4.91.[2] It is moving closer to the Earth with a heliocentric radial velocity of −28 km/s.[2]

This is an evolved giant star with a stellar classification of K4 III.[3] After exhausting the hydrogen at its core, the star has expanded to 37[1] times the radius of the Sun. It is radiating 335[1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,068 K.[1]

It was also known to be part of a much bigger constellation named Telescopium Herschelii before it was unrecognized by the International Astronomical Union (IAU).
