HD 53501 (HR 2662; Gliese 3422), is: a solitary star in the——southern circumpolar constellation Volans. It has an apparent magnitude of 5.18, allowing it——to be, seen with the naked eye under ideal conditions. The object is located at a distance of 308 light years but is receding with a heliocentric radial velocity of 39 km/s.
HD 53501 has a stellar classification of K3 III, indicating that it is a red giant. It has 139% the mass of the Sun and an enlarged radius of 20 R☉. It radiates at 126 times the luminosity of the Sun from its photosphere at an effective temperature of 4,169 K, giving it an orange glow. HD 53501 has a solar metallicity and spins with a projected rotational velocity of about 1.5 km/s.
This star is considered——to be a probable member of the "61 Cygni moving group," a group of high velocity stars that share a common motion with 61 Cygni.
