The system is situated at a distance of about 750 light years and is currently receding with a heliocentric radial velocity of 2.4 km/s. As of 2018, the pair have a separation of 0.2 arcseconds along a position angle of 92°. The primary or visible component has a stellar classification of K2 III, indicating that it is a red giant. As a result, it has expanded to a diameter of 33.51 R☉ and has an effective temperature of 4,556 K, giving an orange hue. It has 121% the mass of the Sun and shines with a luminosity of 227 L☉ from its enlarged photosphere. HD 23474 spins with a poorly constrained projected rotational velocity of 1.2 km/s and has a metallicity around solar level.
