This list of exoplanets discovered in 2023 is a list of confirmed exoplanets that were first reported in 2023. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information.

The first report of an exoplanet within this range was in 1998 for a planet orbiting around Gliese 876 (15.3 light-years (ly) away), and the latest as of 2024 is one around Struve 2398 A (11.5 ly). The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away
The database was updated to include new exoplanets and possible exoplanets, using data from other archives such as the Astrophysics Data System, arXiv and the NASA Exoplanet Archive. [3] The database stopped being updated in mid-2018 and is no longer actively maintained.

The first such project (NameExoWorlds I), in 2015, regarded the naming of stars and exoplanets. [1] 573,242 votes were submitted by members by the time the contest closed on October 31, 2015, and the names of 31 exoplanets and 14 stars were selected from these. [2] Many of the names chosen were based on world history, mythology and literature. [3]
Discovered in 2023, TOI-700 e is a terrestrial exoplanet that NASA claims to be an "earth-like" planet, with 95 percent of the Earth’s radius. Discovered by NASA's TESS (Transitioning Exoplanet Survey Satellite), TOI-700 e has a mass of about 0.818 Earths and takes 27.8 days to orbit once around its star. [13]
It was the youngest transiting exoplanet until the discovery of IRAS 04125+2902 b in 2024. There are relatively few other exoplanets discovered to date with an age this young, all of which are non-transiting (with some that were detected around hot A-type and B-type stars , such as HD 95086 b and HIP 78530 b , however these could be brown ...
