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.

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 ...
First evidence for exoplanet to receive later confirmation. First exoplanets to be confirmed PSR B1257+12 B PSR B1257+12 C: PSR B1257+12: 1992 First super-Earths. [1] These exoplanets orbit a pulsar. First confirmed exoplanet around normal star 51 Pegasi b: 51 Pegasi: 1995 First convincing exoplanet discovered around a Sun-like star. [2]
For exoplanets detected only by radial velocity, the mass value is actually a lower limit. (See Minimum mass for more information.) While the existence of a substellar companion to Gamma Cephei was suspected since 1988, [ 2 ] the planet Gamma Cephei Ab was not confirmed until 2003, [ 3 ] and that is listed as its discovery year in exoplanet ...
The number of known exoplanets officially passed 5,000 on Monday, with NASA confirming the discovery of 65 new worlds. Do you want to hear what that...sounds like?Created by Toronto-based ...
All of the previous exoplanets found to have atmospheres were gaseous planets, not rocky ones. As Webb pushes the frontiers of exoplanet exploration, the discovery of a rocky one with an ...
As of 2024, there are eight official planets in the Solar System per the International Astronomical Union (IAU), [1] which has also established a definition for exoplanets. Several objects formerly considered exoplanets have been found actually to be stars or brown dwarfs.
