HD 122862 (HR 5279) is a solitary star in the southern circumpolar constellation Apus. It has an apparent magnitude of 6.02, allowing it to be faintly seen with the naked eye under ideal conditions. The star is relatively close at a distance of 95 light years, but is approaching the Sun with a radial velocity of −21.11 km/s. HD 122862 is a G-type subgiant with 1.08 times the mass of the Sun and a diameter of 1.58 R☉. It shines at 2.87 times the luminosity of the Sun from its photosphere at an effective temperature of 5,943 K, giving it a yellow glow. HD 122862 has an iron abundance 71% that of the Sun and, at an age of 6.83 billion years, it spins slowly with a projected rotational velocity of 3.1 km/s.
