[2] Based on parallax measurements obtained during the Hipparcos mission, it is approximately 83 light-years (25 parsecs) distant from the Sun.

[16] WDS J19054+1352 is the entry of the wider system of which Zeta Aquilae is a member in the Washington Double Star Catalog.

[11] Epsilon and Zeta Aquilae also bore the Mandarin names Woo /ˈwuː/ and Yuë /ˈjuːeɪ/, derived from and representing the old states Wú (吳) (located at the mouth of the Yangtze River) and Yuè (越) (in Zhejiang province).

[21] In Chinese, 天市左垣 (Tiān Shì Zuǒ Yuán), meaning Left Wall of Heavenly Market Enclosure, refers to an asterism which represents eleven old states in China and is marking the left borderline of the enclosure, consisting of Zeta Aquilae; Delta, Lambda, Mu, Omicron and 112 Herculis; Theta¹ and Eta Serpentis; Nu Ophiuchi, Xi Serpentis and Eta Ophiuchi.

[22] Consequently, the Chinese name for Zeta Aquilae itself is 天市左垣六 (Tiān Shì Zuǒ Yuán liù, English: the Sixth Star of Left Wall of Heavenly Market Enclosure), representing the state mentioned above.

[23] The primary, designated component A, has a stellar classification of A0 Vn,[3] with the luminosity class 'V' indicating is a main sequence star that is generating energy through the nuclear fusion of hydrogen at its core.

[6] Because of the Doppler effect, this rapid rotation makes the absorption lines in the star's spectrum broaden and smear out, as indicated by the 'n' suffix in the stellar class.

[8] The 16th magnitude star WDS J19054+1352E is also considered to be a co-moving companion with a mass of 0.14 M☉, at a projected separation of 38,000 AU from the primary.
