This is an aging K-type giant star with a stellar classification of K4III,^[3] having exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence. At present it has about 60 times the radius of the Sun and is radiating 826 times the Sun's luminosity from its swollen photosphere at an effective temperature of 4,038 K.^[6]
