Beta Virginis (β Vir / β Virginis) is a star in the constellation Virgo. It also has the traditional name Zavijava (also Zavijah). Despite being the beta star of the constellation Virgo it is only the fifth star in order of brightness.
Since it is close to the ecliptic, it can be occulted by the Moon and (very rarely) by planets. The next planetary occultation of Zavijava will take place on 11 August 2069 by Venus.
