HD 122862 (HR 5279) is a solitary star in the southern circumpolar constellation Apus. It has an apparent magnitude of 6.02,[2] 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,[1] but is approaching the Sun with a radial velocity of −21.11 km/s.[5]
HD 122862 is a G-type subgiant[3] with 1.08 times the mass of the Sun[6] and a diameter of 1.58 R☉.[5] It shines at 2.87 times the luminosity of the Sun[5] from its photosphere at an effective temperature of 5,943 K,[6] giving it a yellow glow. HD 122862 has an iron abundance 71% that of the Sun[6] and, at an age of 6.83 billion years,[6] it spins slowly with a projected rotational velocity of 3.1 km/s.[7]
