The annual parallax shift is 21.75 milliarcseconds,[1] which corresponds to a distance of the star of around 150 light-years (46 parsecs) from Earth.

Relatively high proper motion resulted in the star crossing the border from Aquila into Delphinus in 1992.

The star is in the low-northern constellation of Delphinus therefore at least seasonally visible to all but the high southern latitudes.

This star has the traditional name Tso Ke, from the Cantonese 左旗 jo keih meaning "the left flag".

[13] Consequently, ρ Aquilae itself is known as 左旗九 (Zuǒ Qí jiǔ, English: the Ninth Star of Left Flag.
