List of exoplanets discovered before 2000

This is a list of exoplanets discovered before 2000.

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, the planet Gamma Cephei Ab was not confirmed until 2003, 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.
