Psi2 Aurigae
At that distance, the brightness of the star is diminished by 0.07 in magnitude from extinction caused by interstellar gas and dust.[5] Most studies categorized this as a K-type giant star with a stellar classification of K3 III.[3] However, the results of a study published in 2003 list it with a classification of K3 Iab:, which would instead suggest it is a supergiant star.[11] At the estimated distance of this star,[1] this yields a physical size of about 27 times the radius of the Sun.[7] It is radiating 304[6] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,410 K.[8] It was also known to be part of a much bigger constellation named Telescopium Herschelii.
