First Planet Star Year Notes First detected exoplanet later confirmed Gamma Cephei Ab: Gamma Cephei: 1988 (suspected), 2002 (confirmed) First evidence for exoplanet to receive later confirmation. First exoplanets to be confirmed PSR B1257+12 B PSR B1257+12 C: PSR B1257+12: 1992 First super-Earths. [1] These exoplanets orbit a pulsar.
Animation showing exoplanets by year from 1991 until 2022 (March) with a total of 5005 discoveries. [1] An exoplanet (extrasolar planet) is a planet located outside the Solar System. The first evidence of an exoplanet was noted as early as 1917, but was not recognized as such until 2016; no planet discovery has yet come from that evidence. [2]

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.)
This is the list of years when at least one confirmed exoplanets were discovered. This is a container category . Due to its scope, it should contain only subcategories .
