Psi Tauri, which is Latinized from ψ Tauri, is a solitary[9] star in the zodiac constellation of Taurus. It has a yellow-white hue and is visible to the naked eye with an apparent visual magnitude of +5.22.[2] The distance to this system, as determined using an annual parallax shift of Script error: No such module "val". as seen from the Earth,[10] is 91 light years. It is drifting further away with a radial velocity of +9 km/s.
This object is an F-type main sequence star with a stellar classification of F1 V,[3] which indicates it is undergoing core hydrogen fusion. It is about 1.4 billion years old and is spinning with a projected rotational velocity of 45 km/s.[7] The star has 1.6 times the mass of the Sun[5] and 1.4 times its radius.[1] It is radiating 4.8 times the Sun's luminosity from its photosphere at an effective temperature of 7,088 K.[5]
