Xi Piscium (Xi Psc, ξ Piscium, ξ Psc) is a spectroscopic binary star system in the constellation of Pisces, with an apparent magnitude of +4.61. The primary component is an orange K-type giant. It is approximately 191 light years from Earth.
Xi Piscium is moving through the Galaxy at a speed of 30.7 km/s relative to the Sun. Its projected Galactic orbit carries it between 24,100 and 39,700 light years from the center of the Galaxy.
Xi Piscium came closest to the Sun 1.8 million years ago when it had brightened to magnitude 1.77 from a distance of 51 light years.
In Chinese, 外屏 (Wài Píng), meaning Outer Fence, refers to an asterism consisting of refers to an asterism consisting of ξ Piscium, δ Piscium, ε Piscium, ζ Piscium, μ Piscium, ν Piscium and α Piscium. Consequently, ξ Piscium itself is known as 外屏六 (Wài Píng liù, English: the Sixth Star of Outer Fence.)
