ν Tauri , Latinized as Nu Tauri , is a single[ 11] star in the zodiac constellation of Taurus . It is a white-hued star and is visible to the naked eye with an apparent visual magnitude of +3.91.[ 2] This object is located 117 light years from the Sun based on parallax ,[ 1] but is drifting closer with a radial velocity of −6 km/s.[ 6] It is predicted to come to within roughly 18.4 ly of the Sun in around five million years.[ 12]
This object is an A-type main-sequence star with a stellar classification of A0.5Va.[ 4] It is 206[ 8] million years old and is rotating with a projected rotational velocity of 83 km/s.[ 3] The star has 2.25[ 3] times the mass of the Sun and 2.87[ 7] times the Sun's radius . It is radiating 28 times the luminosity of the Sun from its photosphere at an effective temperature of 7,836 K.[ 7]
Nu Tauri has a magnitude 9.21 visual companion at an angular separation 15.9″ .[ 13]
