Rho Aquilae (ρ Aql, ρ Aquilae) is a star in the constellation Delphinus – it moved across the border from Aquila into Delphinus in 1992. [1] It has the traditional name Tso Ke, from the Mandarin 左旗 zuǒqí meaning "the left flag".
In Chinese, 左旗 (Zuǒ Qí), meaning Left Flag, refers to an asterism consisting of ρ Aquilae, α Sagittae, β Sagittae, δ Sagittae, ζ Sagittae, γ Sagittae, 13 Sagittae, 11 Sagittae and 14 Sagittae.[1] Consequently, ρ Aquilae itself is known as 左旗九 (Zuǒ Qí jiǔ, English: the Ninth Star of Left Flag.)[2]
Rho Aquilae is a white A-type main sequence dwarf with an apparent magnitude of +4.94. It is approximately 154 light years from Earth.
