10 Tauri is a single[9] star in the zodiac constellation of Taurus. It can be seen with the naked eye, having an apparent visual magnitude of 4.29.[2] An annual parallax shift of 71.62[1] mas provides a distance estimate of 45.5 light years. It is moving further from the Sun with a radial velocity of +28 km/s[4] and has a relatively high proper motion.[2]
The star has a stellar classification of F8 V,[3] indicating that it is an ordinary F-type main-sequence star that is generating energy through hydrogen fusion in its core region. It is around 5.7[6] billion years old with a rotation period of 17.6 days.[8] The star has 1.14 times the mass of the Sun and 1.6 times the Sun's radius. It is radiating three[6] times the Sun's luminosity from its photosphere at an effective temperature of 6,000 K.[7]
A debris disk has been identified orbiting 10 Tauri, based on excess infrared radiation detected by IRAS/ISO.[10]
10 Tauri was the brightest star in the obsolete constellation Psalterium Georgii (Harpa Georgii).[11]
