ν Virginis, Latinized as Nu Virginis, is a single[9]star in the zodiacconstellation of Virgo, located at the western tip of the classic constellation and nearly due south of the prominent star Denebola.[10] It is a red-hued star with an apparent visual magnitude of 4.04[2] and can be seen with the naked eye. Because the star lies near the ecliptic it is subject to occultations by the Moon.[11]Parallax measurements provide an estimated distance of around 331 light years from the Sun,[1] and it is drifting further away with a radial velocity of +50 km/s.[5]
