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.
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 ...
No name was given to the star in Argelander's announcement, but by October of 1856 it was being called R Aquilae, its variable star designation, in the astronomical literature. [ 9 ] [ 10 ] [ 7 ] 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 ...

The proper motion of Rho Aquilae, for example, carried it across the boundary into Delphinus in 1992. [ 9 ] [ 10 ] A further complication is the use of numeric superscripts to distinguish neighboring stars that Bayer (or a later astronomer) labeled with a common letter.

28 Aquilae is its Flamsteed designation though it also bears the Bayer designation A Aquilae, and the variable star designation V1208 Aquilae. It has an apparent visual magnitude is 5.5, [ 4 ] making this a faint star that requires dark suburban skies to view (according to the Bortle Dark-Sky Scale ).
