 The Ib luminosity class indicates this a lower luminosity supergiant star that has consumed the hydrogen fuel at its core, evolved away from the main sequence, and expanded to about 290 times the Sun's radius.The effective temperature of the star's outer envelope is approximately 4,000 K, which gives it the orange hue of a K-type star.It is a semiregular variable star that varies in apparent magnitude from a high of 2.70 down to 2.85.
