11 Sagittae is a star in the constellation Sagitta. It is a blue giant with a spectral classification of B9III and has evolved off the main sequence and will enter the Hertzsprung gap soon.[citation needed]
Naming
It is in the Chinese asterism 左旗 (Zuǒ Qí), or Left Flag which consists of 11 Sagittae, γ Sagittae, α Sagittae, β Sagittae, δ Sagittae, ζ Sagittae, 13 Sagittae, 14 Sagittae and ρ Aquilae. Consequently, the Chinese name for γ Sagittae itself is 左旗七 (Zuǒ Qí qī, English: the Seventh Star of Left Flag).[citation needed]
