This is an evolved giant star with a stellar classification of K1 III.[3] It has a mild barium anomaly,[12] which may indicate this is a binary star system with a white dwarf companion.[13] The interferometry-measured angular diameter of the visible component is about 2.31±0.03 mas,[14] which, at its estimated distance, equates to a physical radius of about 44 times the radius of the Sun.[6] This star has about four times the mass of the Sun[5] and is radiating 794 times the Sun's luminosity[7] from its enlarged photosphere at an effective temperature of 4,336 K.[6]
