66 Aurigae is a single[7] star located approximately 880 light years away from the Sun in the northern constellation of Auriga. It is visible to the naked eye as a faint, orange hued star with an apparent magnitude of 5.23.[2] This object is moving further from the Earth with a heliocentric radial velocity of +22.6 km/s.[1]
At the age of 107 million years,[3] 66 Aurigae is an evolved giant star, most likely (98% chance) on the horizontal branch,[3] with a stellar classification of K0.5 IIIa.[4] Keenan and Yorka (1987) identified it as a strong–CN star, showing an excess strength of the blue CN bands in the spectrum.[8] Having exhausted the supply of hydrogen at its core, the star has expanded to 48[1] times the Sun's radius. 66 Aurigae has five[3] times the mass of the Sun and is radiating 834[1] times the Sun's luminosity from its swollen photosphere at an effective temperature of 4,475 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).
