Psi8 Aurigae (ψ8 Aur, ψ8 Aurigae) is the Bayer designation for a binary star[3] system in the northern constellation of Auriga. The pair have a combined apparent visual magnitude of 6.319[2] and, based upon parallax measurements, they are approximately 210 light-years (64 parsecs) distant from the Earth.[1]
The combined spectrum of the pair match a stellar classification of F5 V.[4] The primary component may be an A-type star with an apparent magnitude of 6.47,[3] while the fainter, 8.96 magnitude secondary is possibly a G-type star. The pair orbit each other with a period of 271.1 years at an angular separation of 0.793 arcseconds.[3]
