HD 185269 is a stellar triple system[2] approximately 171 light-years away in the constellation Cygnus. It is easily visible to binoculars, but not the naked eye.
The primary star is a quarter more massive and four times more luminous than our local star. The spectrum of the star is G0IV.

Planetary system[edit]
The Jupiter-mass hot Jupiter was independently discovered orbiting the primary star by two different teams using doppler spectroscopy. One group led by Claire Moutou used the ELODIE spectrograph at the Haute-Provence Observatory in France while John Asher Johnson and collaborators used the Coudé Auxiliary and C. Donald Shane telescopes at Lick Observatory in California.[3][4] The planet takes 6.8 days to orbit at 0.077 AU from the primary star in an eccentric orbit.
