This object is an aging giant star with a stellar classification of K3 III,[3] having exhausted the supply of hydrogen at its core and expanded to 11[1] times the Sun's radius. It is 5.3[2] billion years old with 1.36[2] times the mass of the Sun. The star shines with 49[1] times the Sun's luminosity; this energy is being radiated from the photosphere at an effective temperature of 4,449 K,[2] giving it the orange-hued glow of a K-type star.
