This is an aging giant star with a stellar classification of K2 IIIa, having already consumed the hydrogen at its core and evolved away from the main sequence. It has nearly five times the mass of the Sun but has expanded to around 100 times the Sun's radius. The star is radiating 2,889 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,200 K.
