51 Arietis is a star in the northern constellation of Aries. 51 Arietis is the Flamsteed designation. It is a dim, yellow-hued star – a challenge to view with the naked eye, having an apparent visual magnitude of 6.6.[2] Based upon parallax measurements, the star is located at an estimated distance of 67.3 light-years (20.6 parsecs) from the Sun.[8] It is receding from the Earth with a heliocentric radial velocity of +9.5 km/s,[5] and is a member of the IC 2391 moving group.[3] This is an ordinary 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 Sun's radius.[2] It is 1.4[5] billion years old with a leisurely rotation rate, showing a projected rotational velocity of 4 km/s.[4] The atmospheric metallicity is higher than solar.[6] The star radiates 92%[6] of the Sun's luminosity from its photosphere at an effective temperature of 5,666 K.[6] This heat gives it the golden-hued glow of a G-type star.[9] References
