16 Arietis is a star in the northern constellation of Aries. 16 Arietis is the Flamsteed designation, abbreviated 16 Ari. Its apparent magnitude is 6.01. Based upon the annual parallax shift of 6.39±0.05 mas,[2] this star is approximately 510 ly distant from Earth. The brightness of this star is diminished by 0.40 in magnitude from extinction caused by interstellar gas and dust.[5] This is an evolved giant star with a stellar classification of K3 III.[3]
