60 Arietis is a star in the northern constellation of Aries. 60 Arietis is the Flamsteed designation. It has an apparent visual magnitude of 6.14,[2] making it a challenge to view with the naked eye. Based upon an annual parallax shift of 9.57±0.05 mas, this star is located 341 light-years (105 parsecs) away from the Sun. It is receding from the Earth with a heliocentric radial velocity of +24 km/s.[1]
This object is an aging giant star with a stellar classification of K3 III,[3] having exhausted the supply of hydrogen at its core and expanded to 11[1] times the Sun's radius. It is 5.3[2] billion years old with 1.36[2] times the mass of the Sun. The star shines with 49[1] times the Sun's luminosity; this energy is being radiated from the photosphere at an effective temperature of 4,449 K,[2] giving it the orange-hued glow of a K-type star.
