This is an evolved giant star with a stellar classification of K1 III.[3] It has a mild barium anomaly,[10] which may indicate this is a binary star system with a white dwarf companion.[11] The interferometry-measured angular diameter of the visible component is about 2.31±0.03 mas,[12] which, at its estimated distance, equates to a physical radius of about 44 times the radius of the Sun.[6] This star has four[5] times the mass of the Sun and is radiating 761[2] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,370 K.[5]
