[1] For exoplanets detected only by radial velocity, the mass value is actually a lower limit.
While the existence of a substellar companion to Gamma Cephei was suspected since 1988,[2] the planet Gamma Cephei Ab was not confirmed until 2003,[3] and that is listed as its discovery year in exoplanet databases.
Thus, this planet is in the List of exoplanets discovered between 2000–2009.
HD 114762 b was once considered as the first discovered exoplanet.
Found in 1989 by a team led by David Latham, it is now known to be a red dwarf star.
