Xi Virginis (ξ Vir, ξ Virginis) is a solitary[11] star in the zodiac constellation of Virgo. It is bright enough to be seen with the naked eye, having an apparent visual magnitude of 4.83.[2] The distance to this star is about 122 light years, as determined from parallax readings.[1]
Xi Virginis is an A-type main sequence star with a stellar classification of A4 V.[3] It has an estimated age of 480[9] million years and is spinning rapidly with a projected rotational velocity of 130 km/s.[3] It has about 150%[7] the Sun's radius and shines with 12.6[8] times the luminosity of the Sun.
