This is a list of exoplanets. As of 28 January 2021[ref], there are 4,341 confirmed exoplanets, most of which were discovered by the Kepler space telescope. There are an additional 2,366 potential exoplanets from Kepler's first mission yet to be confirmed, as well as 889 from its "Second Light" mission and 1,385 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.
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.
Methods of detection
- Astrometry: 1 (0.0%)
- Direct imaging: 51 (1.2%)
- Radial velocity: 824 (19.0%)
- Transit: 3,306 (76.2%)
- Transit-timing variation: 21 (0.5%)
- Eclipse timing variation: 16 (0.4%)
- Microlensing: 106 (2.4%)
- Pulsar timing variation: 7 (0.2%)
- Pulsation timing variation: 2 (0.0%)
- Orbital brightness modulation: 6 (0.1%)
- Disk kinematics: 1 (0.0%)
About 97% of all the confirmed exoplanets have been discovered by indirect techniques of detection, mainly by radial velocity measurements and transit monitoring techniques.
