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 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.

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 ...
Astrometry has been used to discover a handful number of exoplanets, mostly gas giants more massive than Jupiter. It is based on measuring a star's proper motion, and seeing how that position changes over time: a planet with a sufficiently large mass is able to gravitationally pull its host star, making its proper motion vary over large timescales.
A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, according to a new study.
Scientists say Speculoos-3 b exoplanet orbits a star that will be one of the last to shine when the universe grows cold and dark New Earth-sized planet discovered next to star that will outlive ...
On 6 January 2015, NASA announced the 1000th confirmed exoplanet discovered by the Kepler Space Telescope. Three of the newly confirmed exoplanets were found to orbit within habitable zones of their host stars: two of the three, Kepler-438b and Kepler-442b, are near-Earth-size and likely rocky; the third, Kepler-440b, is a super-Earth.
