HD 60150 has a classification of K5 III,[3] indicating that it is a red giant. It has 1.2 times the mass of the Sun[7] but has expanded to 41 times its girth.[8] It radiates 329 times the luminosity of the Sun[9] from its swollen photosphere at an effective temperature of 4,007 K,[8] giving it a reddish orange hue. HD 60150 is metal enriched, with an iron abundance 38% greater than the Sun.[8] It spins leisurely with projected rotational velocity of about 1.8 km/s.[10]
