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.[4]

This is an aging giant star with a stellar classification of G6 III,[3] most likely on the horizontal branch.[8] It is 437[3] million years old with 2.77[3] 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.[6]

A magnitude 11.54 companion star is located at an angular separation of 100.90″ along a position angle of 299°, as of 2013.[9]
