Rho Aquilae, ρ Aquilae, is the Bayer designation for a star in the northern constellation of Delphinus. It has an apparent visual magnitude of 4.94 [ 2 ] and is bright enough to be seen with the naked eye in good conditions.
Aquila is a constellation on the celestial equator. Its name is Latin for 'eagle' and it represents the bird that carried Zeus/Jupiter's thunderbolts in Greek-Roman mythology. Its brightest star, Altair, is one vertex of the Summer Triangle asterism. The constellation is best seen in the northern summer, as it is located along the Milky Way.
R Aquilae is a variable star in the equatorial constellation of Aquila. It is located approximately 760 light years distant from the Sun [ 6 ] and is drifting further away with a radial velocity of 35 km/s. [ 5 ]
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 ]
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.
Altair in comparison with the Sun. Along with β Aquilae and γ Aquilae, Altair forms the well-known line of stars sometimes referred to as the Family of Aquila or Shaft of Aquila. [17]: 190 Altair is a type-A main-sequence star with about 1.8 times the mass of the Sun and 11 times its luminosity.
Xi Aquilae (ξ Aquilae, abbreviated Xi Aql, ξ Aql), officially named Libertas / ˈ l ɪ b ər t æ s /, [11] is a red-clump giant star located at a distance of 186 light-years (57 parsecs) from the Sun in the equatorial constellation of Aquila.
Lambda Aquilae has nearly five times the mass of the Sun [5] and eight times the Sun's radius. [6] It is emitting 851 [5] times the luminosity of the Sun from its outer atmosphere at an effective temperature of 14,500 K, [10] giving it the blue-white hue of a B-type star. [11] The projected rotational velocity of this star is 55 km/s. [7]
