This is an evolved K-type giant star with a stellar classification of K1 III.[4] It is a red clump giant, which indicates it is on the horizontal branch and is generating energy through helium fusion at its core.[3] The star is 4.1 billion years old with 1.34[7] times the mass of the Sun and 13 times the Sun's radius. It is radiating 69[1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,665 K.[8]
