Ascella
Zeta Sagittarii (ζ Sagittarii, abbreviated Zeta Sgr, ζ Sgr) is a triple star system and the third-brightest star in the constellation of Sagittarius after Kaus Australis and Nunki. Based upon parallax measurements, it is about 88 light-years (27 parsecs) from the Sun.
The three components are designated Zeta Sagittarii Aa (officially named Ascella , the traditional name for the entire system), Ab and B. The Washington Double Star Catalog cites a component separated 72.3" from the system, but it is a background star unrelated to the pair.
