HD 185269 is a stellar triple system[4] approximately 170 light-years away in the constellation Cygnus. It is easily visible to binoculars, but not the naked eye.

The primary star is a third more massive[2] and four times more luminous than the Sun.[citation needed] The spectrum of the star is G0IV.[2] About 4.5 arcseconds away are the two other stars, which are much less massive than the Sun. The primary has a mass of 0.165 M, while the secondary has a mass of 0.154 M.[4]
