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