Tau Virginis (τ Vir, τ Virginis) is a single[13] star in the zodiac constellation Virgo. With an apparent visual magnitude of 4.28,[2] it is faintly visible to the naked eye. The distance to Tau Virginis, based upon parallax measurements, is approximately 225 light years with a margin of error of ±3 light years.
This star has a stellar classification of A2IV/V,[3] which matches the spectrum of an A-type main sequence star mixed with spectral traits of a subgiant. It is about 700[7] million years old and is spinning rapidly with a projected rotational velocity of 186 km/s.[11] The star has nearly double[7] the mass of the Sun and about 160% of the Sun's radius.[8] It shines with 70[9] times the luminosity of the Sun and has an effective temperature of 8413 K in its outer atmosphere.[7]
