This list of exoplanets discovered in 2024 is a list of confirmed exoplanets that were first reported in 2024. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information.

It was discovered in 2024 by Italian amateur astronomers Giuseppe Conzo and Mara Moriconi using the transit method with TESS data. At the beginning, a single transit event was identified, so the extrasolar planet was first classified as a candidate with TOI-6883.01 [1] nomenclature.
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
The most massive transiting exoplanet is KELT-1b which masses 27.23 M J (making it a brown dwarf) while the least massive is Kepler-42d which masses less than 0.003 M J or 0.9 M E. [2] The largest exoplanet known is HAT-P-32b which is 2.037 R J. The smallest exoplanet known is also Kepler-42d which is 0.051 R J or 0.57 R 🜨.
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.

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.
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]
