60 Aquarii is a star located 375 light years away from the Sun in the equatorial constellation of Aquarius. 60 Aquarii is its Flamsteed designation. It is visible to the naked eye as a dim, yellow-hued star with an apparent visual magnitude of 5.89.[2] The star is moving closer to the Earth with a heliocentric radial velocity of –8 km/s.[5]
This is an aging giant star with a stellar classification of G6 III,[4] most likely on the horizontal branch.[3] It is 437[4] million years old with 2.77[4] times the mass of the Sun. Having exhausted the hydrogen at its core, this star has evolved away from the main sequence and expanded to 11[1] times the Sun's radius. It is radiating 65[1] times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,820 K.[7]
A magnitude 11.54 companion star is located at an angular separation of Script error: No such module "val". along a position angle of 299°, as of 2013.[9]
