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.
Rho Aquilae at magnitude 4.94 [26] is at about 150 light-years away. [26] Due to its proper motion it has been in the (round-figure parameter) bounds of the constellation since 1992. [ 27 ] It is an A-type main sequence star with a lower metallicity than the Sun. [ 28 ]
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.
Among the remaining stars, the nearer ones exhibit proper motion, so it is only a matter of time before some of them cross a constellation boundary and switch constellations as a consequence. In 1992, Rho Aquilae became the first star to have its Bayer designation "invalidated" by moving to a neighbouring constellation—it is now a star of the ...

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]
Altair is the brightest star in the constellation Aquila. α Aquilae (Latinised to Alpha Aquilae) is the star's Bayer designation. The traditional name Altair has been used since medieval times. It is an abbreviation of the Arabic phrase النسر الطائر Al-Nisr Al-Ṭa'ir, "the flying eagle ". [22]
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.
