This list of exoplanets discovered in 2021 is a list of confirmed exoplanets that were first observed in 2021. For exoplanets detected only by radial velocity , the listed value for mass is a lower limit.
The exoplanets were found using a statistical technique called "verification by multiplicity". 95% of the discovered exoplanets were smaller than Neptune and four, including Kepler-296f, were less than 2 1/2 the size of Earth and were in habitable zones where surface temperatures are suitable for liquid water.

The NASA Exoplanet Archive is an online astronomical exoplanet catalog and data service that collects and serves public data that support the search for and characterization of extra-solar planets (exoplanets) and their host stars.
Over 5,000 exoplanets have been confirmed by previous data, but LHS 475 b is the first to be confirmed by observations with the telescope. The exoplanet was stated to be 41 light-years away in the ...
All of the previous exoplanets found to have atmospheres were gaseous planets, not rocky ones. As Webb pushes the frontiers of exoplanet exploration, the discovery of a rocky one with an ...
TOI-2257 b is an extremely eccentric (0.496) [2] exoplanet in or near the circumstellar habitable zone of the star TOI-2257, 188 light-years away. It is likely a sub-Neptune exoplanet, with a mass of 5.71 Mearth and a radius of 2.19 Rearth. [3]
This list of exoplanets discovered in 2022 is a list of confirmed exoplanets that were first reported in 2022. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information. On 31 March 2022, K2-2016-BLG-0005Lb was reported to be the most distant exoplanet found by Kepler to ...
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]
