Psi7 Aurigae

Psi⁷ Aurigae (ψ⁷ Aur, ψ⁷ Aurigae) is the Bayer designation for a single star in the northern constellation of Auriga. It is a dim, naked eye star with an apparent visual magnitude of 5.02. Based upon parallax measurements made during the Hipparcos mission, it is approximately 379 light-years (116 parsecs) distant from Earth.

This is an evolved giant star with a stellar classification of K3 III. The measured angular diameter of this star, after correction for limb darkening, is 1.96 ± 0.04 mas. At it estimated distance, this yields a physical size of about 24 times the radius of the Sun. The outer envelope shines with an effective temperature of 4,300, giving it the orange-hued glow of a K-type star.
