Psi7 Aurigae, Latinized from ψ7 Aurigae, is a star in the northern constellation of Auriga. It is a dim, naked eye star with an apparent visual magnitude of 5.02. Based upon Gaia Data Release 2 parallax values, it is approximately Template:Convert from Earth.
ψ7 Aurigae is a giant star with a stellar classification of K3 III.[1] The measured angular diameter of this star, after correction for limb darkening, is Template:Nowrap.[2] At its estimated distance,[3] this yields a physical size of about 24 times the radius of the Sun.[4] The outer envelope has an effective temperature of 4,300,[5] giving it an orange colour and a classification as a K-type star.[6] Although cooler than the sun, its larger size means that it is more luminous, emitting in total 217 times as much electromagnetic radiation.
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).
