Eta Virginis (η Vir / η Virginis) is a star in the constellation Virgo. It also has the traditional name Zaniah.
Zaniah is about 204 light years distant from the Sun, and has apparent magnitude +3.9 and is of spectral type A2IV.
Although the star looks single in any telescope lunar occultations have shown this star to be a very close triple star system consisting of two stars only 0.5 AU apart with a third slightly more distant star.
Because Zaniah is near the ecliptic, it can be occulted by the Moon and (very rarely) by planets. The last occultation by a planet took place on September 27, 1843 by Venus, which will occult it again on November 19, 2445.
