R Aquilae is an aging red giant on the asymptotic giant branch [3] with a stellar classification that varies over time, between M5e and M9e, [2] where the 'e' suffix indicates emission features in the spectrum. The cooler spectral types occur near the minimum visual magnitude, and the hottest near maximum. [11]
Theta Aquilae (θ Aql, θ Aquilae), also named Antinous, [8] is a binary star in the constellation Aquila. The combined apparent visual magnitude of the pair is 3.26, [ 2 ] making it the fourth-brightest member of the constellation.
Zeta Aquilae, or ζ Aquilae, is a binary star [8] system in the equatorial constellation of Aquila. It is readily visible with the naked eye, being of the third magnitude. [ 2 ] Based on parallax measurements obtained during the Hipparcos mission, it is approximately 83 light-years (25 parsecs ) distant from the Sun . [ 1 ]
Delta Aquilae, Latinized from δ Aquilae, is a binary star system in the equatorial constellation of Aquila. It has an apparent visual magnitude of 3.4 [2] and, based upon parallax measurements, is located at a distance of about 50.6 light-years (15.5 parsecs) from Earth. [1] It is drifting closer with a radial velocity of −30 km/s. [6]
23 Aquilae is a binary star [8] system in the equatorial constellation of Aquila. 23 Aquilae is its Flamsteed designation . It is at a distance of about 400 light-years (120 parsecs ) with an apparent visual magnitude of 5.10, [ 2 ] which is bright enough to be faintly visible to the naked eye as an orange-hued star.
