Nu Sagittarii

The Bayer designation Nu Sagittarii (Nu Sgr, ν Sagittarii, ν Sgr) is shared by two star systems, ν¹ Sagittarii and ν² Sagittarii, in the constellation Sagittarius. The two stars are separated by 0.23° in the sky. Nu Sagittarii also has the traditional name Ain al Rami.

Nu Sagittarii is often cited as one of the earliest identified double stars. In the Almagest, Ptolemy describes the star as "nebulous and double", referring to the double nature of the star, as well as the nearby globular cluster NGC 6717.
