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]
