HD 86267, also known as HR 3932, is a solitary orange-hued star located in the southern constellation Antlia. It has an apparent magnitude of 5.82, allowing it to be faintly seen with the naked eye. Parallax measurements place it a distance of 514 light years and it is currently receding with a heliocentric radial velocity of 3.7 km/s.
HD 86267 has a stellar classification of K1 III, indicating that it is a red giant. At present it has 1.73 times the mass of the Sun but has expanded to 19.7 times its girth. It shines with a luminosity of 158 L☉ from its enlarged photosphere at an effective temperature of 4,430 K. It is a member of the old disk population, having a metallicity 71% that of the Sun. The value means that it is metal deficient. Its current rotation rate is too low to be measured accurately.
