This is an evolved giant star with a stellar classification of K0 III,^[3] having exhausted the hydrogen at its core and expanded away from the main sequence. It is a red clump star, which indicates it is generating energy through helium fusion at its core.^[5] This object is 3.4 billion years old with 1.7^[6] times the mass of the Sun and 12^[7] times the Sun's radius. It is radiating 69 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4706 K.^[6]
