HD 86267 has a stellar classification of K1 III,[4] indicating that it is a red giant. At present it has 1.73 times the mass of the Sun[7] but has expanded to 19.7 times its girth.[8] It shines with a luminosity of 158 L☉ from its enlarged photosphere at an effective temperature of 4,430 K.[7] It is a member of the old disk population, having a metallicity 71% that of the Sun.[10] The value means that it is metal deficient. Its current rotation rate is too low to be measured accurately.[11]
