Eta Virginis (η Virginis, abbreviated Eta Vir, η Vir) is a triple star system in the zodiac constellation of Virgo. From parallax measurements, it is about from the Sun. It has a combined apparent visual magnitude of 3.89, bright enough to be seen with the naked eye in dark skies.

The system consists of a binary pair designated Eta Virginis A together with a third companion, Eta Virginis B. A's two components are themselves designated Eta Virginis Aa (officially named Zaniah , the traditional name of the system) and Ab. Provided by Wikipedia
