On February 26, 2014, NASA announced the discovery of 715 newly verified exoplanets around 305 stars by the Kepler Space Telescope. 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 ...

This list of exoplanets discovered in 2025 is a list of confirmed exoplanets that were first reported in 2025. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information.
The 2006 IAU redefinition of planet excludes the possibility of double planets. [24] [25] [26] 15760 Albion: 1992 unknown Trans-Neptunian object: When discovered, these bodies were briefly hailed as the tenth and eleventh planets by the press, but it was then decided that 15760 Albion was the prototype of trans-Neptunian objects or cubewanos ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
This method works best for young planets that emit infrared light and are far from the glare of the star. Currently, this list includes both directly imaged planets and imaged planetary-mass companions (objects that orbit a star but formed through a binary-star-formation process, not a planet-formation process).
The planets were detected by observing small dips in the star's brightness when they crossed in front of it from our vantage point. The innermost planet takes about nine days to orbit the star ...
The first extrasolar planet found to have a density compatible with being a rocky planet is CoRoT-7b in 2009. 55 Cancri e was found to be a terrestrial planet in 2011. First super-Earth orbiting a main sequence star [NB 2] Gliese 876 d: Gliese 876: 2005 Orbits a red dwarf star. First icy extrasolar planet orbiting a main sequence star OGLE-2005 ...
