HD 114762 b

The companion was detected through a radial-velocity signal from the star HD 114762. Latham and colleagues reported the signal in 1989, making it one of the earliest objects found through this method. [NASA Exoplanet Archive](https://exoplanetarchive.ipac.caltech.edu/overview/HD%20114762)

The measured orbital period is about 83.9 days, with a calculated separation near 0.36 astronomical units. Its orbit is therefore much shorter than Earth's year even though the object is classified as a long-period companion relative to many close-in exoplanets.

No. Radial velocity gives a minimum mass of roughly 11 Jupiter masses, and the current NASA Exoplanet Archive overview lists its disposition as False Positive Planet because the true mass may be much higher. [NASA Exoplanet Archive](https://exoplanetarchive.ipac.caltech.edu/overview/HD%20114762)

Radial velocity measures the star's motion along our line of sight, producing a value written as mass times sin of the orbital inclination. If the orbit is viewed nearly face-on, the actual companion can be far more massive than the approximately 11 Jupiter-mass minimum.
