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 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.
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 ...
TOI-1431 b, also known as MASCARA-5b, is an ultra-hot Jupiter exoplanet orbiting TOI-1431 in the constellation of Cepheus. It has an orbital period of 2.7 days. [ 1 ] Its dayside temperature is 2,700 K (2,427 °C), making it hotter than 40% of stars in our galaxy. [ 2 ]
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]
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. See Minimum mass for more information.
This signal was formally proposed to be a candidate exoplanet by Faria et al. in a follow-up paper published in February 2022. [ 4 ] [ 1 ] Proxima d is a sub-Earth at least one-quarter of the mass of Earth (or twice the mass of Mars ), orbiting at roughly 0.029 AU (4.3 million km; 2.7 million mi) every 5.1 days. [ 4 ]
