60 Herculis is a single [13] star located 134 [1] light years away from the Sun in the northern constellation of Hercules, [12] and is positioned just seven [14] degrees away from Rasalgethi (Alpha Herculis). It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 4.871. [2] This star is moving closer to the Earth with a heliocentric radial velocity of −4 km/s. [8]
Abt and Morrell (1995) assigned this star a stellar classification of A3V, [4] matching an ordinary A-type main-sequence star. However, earlier studies gave it a luminosity class of IV, [5] which suggested it is a subdwarf star. It has a projected rotational velocity of 117 km/s, [3] which is creating an equatorial bulge that is 5% larger than the star's polar radius. [15] The star is 327 [11] million years old with 1.9 [3] times the Sun's mass. It is radiating 17 [3] times the luminosity of the Sun from its photosphere at an effective temperature of 8,299 K. [3]
