Theta Sagittae

The binary pair consists of two stars separated by 502 AU. The primary, component A, is an F-type main sequence star with a stellar classification of F3V. This star is about two billion years old with 52% more mass than the Sun. It forms a double star with a magnitude 8.85 companion, which is located at an angular separation of 11.58 arc seconds along a position angle of 331.1°, as of 2011. The star is sometimes described as a triple star, with a 7th magnitude companion 91″ away. This is an unrelated giant star much further away than the close pair. A fainter star separated by nearly 3′ was also listed as a companion by Struve, again just an accidental optical association.
