Xi Arietis (ξ Ari, ξ Arietis) is the Bayer designation for a star in the northern constellation of Aries. It has an apparent visual magnitude of 5.46, and so is dimly visible to the naked eye. Based upon an annual [2 ] parallax shift of 3.74 ± 0.29 , mas it is 872 ± 68 [1 ] light-years (267 ± 21 parsecs) distant from the Earth.
spectrum of this star matches a stellar classification of B7 IV, indicating that it is a [3 ] subgiant star that has exhausted the supply of hydrogen at its core and is in the process of evolving into a giant star. Xi Arietis was once a designation for Psi Ceti (ψ Cet, ψ Ceti). [5 ]
