The stellar classification of this star is K0 III,[3] matching an evolved giant star that has exhausted the hydrogen at its core and expanded. It is 2.5 billion years old with 1.6 times the mass of the Sun and has grown to five times the Sun's radius. The star is radiating 14 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,931 K.[4]
