The ECWG's rules for naming exoplanets are identical to those adopted by the Minor Planet Center for minor planets. [2] Names are a single word consisting of sixteen characters or less, pronounceable in some language, non-offensive, and not identical to existing proper names of astronomical objects. [3]

These are lists of planets.A planet is a large, rounded astronomical body that is neither a star nor its remnant. The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk.
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. [5] In 1991 it was reported an exoplanet 10 times the mass of Earth was discovered around the pulsar, PSR B1829-10. [6]
Exoplanets have been discovered using several different methods for collecting or combining direct images to isolate planets from the background light of their star. Non-Redundant Aperture Masking Interferometry is a method of combining the views of multiple telescopes into a single image, while the other methods are algorithms for combining ...

This list of exoplanets discovered in 2020 is a list of confirmed exoplanets that were first observed in 2020. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information.
