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,[2] and so is dimly visible to the naked eye. Based upon an annual parallax shift of 3.74 ± 0.29 mas,[1] it is 872 ± 68 light-years (267 ± 21 parsecs) distant from the Earth.
The spectrum of this star matches a stellar classification of B7 IV,[3] indicating that it is a 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]
