Lists of exoplanets
This is a list of exoplanets. As of 5 September 2018[ref] there are 3,778 confirmed exoplanets.[1] The majority of these planets were discovered by the Kepler spacecraft. In addition to the confirmed exoplanets, there are 2,244 potential exoplanets from its first mission that are yet to be confirmed, and 493 from its "Second Light" mission.[2]

Nomenclature
The convention for naming 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.[3] 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 "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.
