}}{{Starbox end}}Phi Aurigae, Latinized from φ Aurigae, is a giant star in the northern constellation of Auriga. It is faintly visible to the naked eye with an apparent visual magnitude of 5.089.[3] It lies {{val|10|ul='}} from another faint naked-eye star HD 35520, between the three open clusters M36 and M38, and NGC 1893.
The distance to this star, as determined from parallax measurements, is approximately {{Convert|480|ly|pc|abbr=off|lk=on}} with a 10 light-year margin of error.[ This is an evolved giant star with a stellar classification of K3 IIIp[4] and an estimated radius equal to 16 times the radius of the Sun. The outer envelope has an effective temperature of 4,367 K,[4] giving it the cool orange-hued glow of a K-type star.]
