Star HD 187123

    HD 187123 b is a typical "hot Jupiter" located approximately 150 light-years away in the constellation of Cygnus, orbiting the star HD 187123. It has a mass about half that of Jupiter and it orbits in a very tight, round orbit around the star every three days. [2] [3]

    The star has also been monitored for possible transits by the planet, but none was found.

    The presence of water has been detected in the atmosphere of HD 187123 b with high confidence. [4]
