HD 53501 (HR 2662; Gliese 3422), is a solitary[10] star in the southern circumpolar constellation Volans. It has an apparent magnitude of 5.18,[2] allowing it to be seen with the naked eye under ideal conditions. The object is located at a distance of 308 light years[1] but is receding with a heliocentric radial velocity of 39 km/s.[5]

HD 53501 has a stellar classification of K3 III,[3] indicating that it is a red giant. It has 139% the mass of the Sun and an enlarged radius of 20 R☉.[6] It radiates at 126 times the luminosity of the Sun[7] from its photosphere at an effective temperature of 4,169 K,[6] giving it an orange glow. HD 53501 has a solar metallicity[8] and spins with a projected rotational velocity of about 1.5 km/s.[9]

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.[11]
