  HD 174387 has a stellar classification of M0 III, indicating that it is an ageing red giant. Due to its evolved state, the star has expanded to a diameter of 82.63 $R_☉.$ At present it has 114% the mass of the Sun and shines 902 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 3,929 K, giving a red hue when viewed. HD 174387's metallicity is estimated to be 91% that of the Sun. The star is suspected to be variable, ranging from magnitudes 5.59 to 5.63 in the Hipparcos passband.
