This is a list of exoplanets discovered before 2000.[1]
For exoplanets detected only by radial velocity, the mass value is actually a lower limit. (See Minimum mass for more information.)
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.
Bodies previously considered as candidates
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.[5]
