51 Arietis (abbreviated 51 Ari) is a star in the northern constellation of Aries. 51 Arietis is the Flamsteed designation. It has an apparent visual magnitude of 6.6[2] and is an estimated 67.3 light-years (20.6 parsecs) distant from the Earth.[1] This is a G-type main sequence star with a stellar classification of G8 V.[3] Similar to the Sun, it has 1.04 times the mass and 0.99 times the radius.[2] It radiates 92%[5] of the Sun's luminosity from its outer atmosphere at an effective temperature of 5,666 K.[5] This heat gives it the golden-hued glow of a G-type star.[7]
