This star has a spectral type of K1III,[3] implying a K-type giant. These types of stars are generally reddish-colored stars with spectral types from K to M, with radii that are 10 to 100 times larger than the Sun.[9] The "CNII" in its spectral type indicates strong cyanogen signature in its outer atmosphere.[10][11] The star is radiating 144[6] times the Sun's luminosity from its enlarged photosphere.
