This is a red giant star with a stellar classification of M0 III. It is most likely on the red-giant branch of its evolutionary lifespan, burning hydrogen in its shell.
It is around 2.35 billion years old with an estimated 1.37 times the mass of the Sun and roughly 55 times the Sun's radius. The star is radiating about 562 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 3,862 K.Naming
