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. Name Mass (M J) Radius (R J) Period (days) Semi-major axis (AU) Temp. (K) Discovery method Distance (ly) Host star mass (M ☉) Host star temp. (K ...

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 [3] The database stopped being updated in mid-2018 and is no longer actively maintained.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]
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
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 ...
The Exoplanet Archive serves photometric time-series data from surveys that aim to discover transiting exoplanets, such as the Kepler Mission and CoRoT. The database provides access to over 22 million light curves from space and ground-based exoplanet transit survey programs, including: Kepler and K2 Public Survey Data; CoRoT Exoplanet Survey data
