Pi Piscium (π Piscium) is a solitary,[8] yellow-white hued star in the zodiac constellation of Pisces. It is faintly visible to the naked eye, having an apparent visual magnitude of 5.60.[2] Based upon an annual parallax shift of 28.50 mas as seen from Earth,[1] it is located about 1114 light years from the Sun. It is a member of the thin disk population of the Milky Way.[5]

This is an ordinary F-type main-sequence star with a stellar classification of F0 V.[3] At the estimated age of two billion years,[6] it is about 55% of the way through its main sequence lifetime[4] and still has a relatively high rate of spin with a projected rotational velocity of 105.9 km/s.[2] The star has 1.5[4] times the mass of the Sun and is radiating 6.3[4] times the Sun's luminosity at an effective temperature of 6,850 K.[2]
