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.
Ptolemy catalogued 19 stars jointly in this constellation and in the now obsolete constellation of Antinous, which was named in the reign of the emperor Hadrian (AD 117–138), but sometimes erroneously attributed to Tycho Brahe, who catalogued 12 stars in Aquila and seven in Antinous. Hevelius determined 23 stars in the first [4] and 19 in the ...
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 light curve. 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]
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 ]
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.
24 Aquilae (abbreviated 24 Aql) is a star in the equatorial constellation of Aquila. 24 Aquilae is its Flamsteed designation. It is located at a distance of around 434 light-years (133 parsecs) [1] from Earth and has an apparent visual magnitude of 6.4. [2] According to the Bortle Dark-Sky Scale, this star is just visible to the naked eye in ...
