List of exoplanets

This is a list of exoplanets. As of 1 April 2022, there are 4,984 confirmed exoplanets in 3,673 planetary systems, with 815 systems having more than one planet. Most of these were discovered by the Kepler space telescope. There are an additional 2,058 potential exoplanets from Kepler's first mission yet to be confirmed, as well as 1,024 from its "Second Light" mission and 3,505 from the Transiting Exoplanet Survey Satellite (TESS) mission.
For yearly lists on physical, orbital and other properties, as well as on discovery circumstances and other aspects, see § Specific exoplanet lists.
== Nomenclature ==
The convention for designating exoplanets is an extension of the system used for designating multiple-star systems as adopted by the International Astronomical Union (IAU). For exoplanets orbiting a single star, the IAU designation is formed by taking the designated or proper name of its parent star, and adding a lower case letter. Letters are given in order of each planet's discovery around the parent star, so that the first planet discovered in a system is designated "b" (the parent star is considered to be "a") and later planets are given subsequent letters. If several planets in the same system are discovered at the same time, the closest one to the star gets the next letter, followed by the other planets in order of orbital size. A provisional IAU-sanctioned standard exists to accommodate the designation of circumbinary planets. A limited number of exoplanets have IAU-sanctioned proper names. Other naming systems exist.
