HD 114762 b is a massive, gaeous extrasolar planet orbiting the binary star HD 114762. It is approximately 126 light-years (38.6 parsecs) away from Earth in the constellation of Coma Berenices. It is a companion to the late F-type main-sequence star of HD 114762. It was discovered in 1989 by David Latham and confirmed in October 1991.
The planet orbits its host star every 83.9 days at an approximate distance of 0.35 AU. It has an eccentricity of 0.34. The orbit is similar to Mercury, although it is twice as eccentric. Depending on the inclination angle, it has either a minimum mass of 11.069 Jupiter mass (90°), and a maximum mass of 63.2 Jupiter mass (10°).
HD 114762 b is one of the first extrasolar planets ever found, predating both the 1992 pulsar planets around PSR B1257+12 and the main-sequence yellow dwarf star 51 Pegasi, although Gamma Cephei Ab predates it. In 2012, its status as an extrasolar planet was confirmed.
