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]
This is a list of exoplanets discovered before 2000. [1] ... HD 114762 b was once considered as the first discovered exoplanet. Found in 1989 by a team led by David ...
These astronomical tables were used and updated during the following three centuries, as the main source of astronomical data, mainly to calculate ephemerides (which were in turn used by astrologers to cast horoscopes). [55] c. 1300 – Jewish astronomer Levi ben Gershon (Gersonides) recognized that the stars are much larger than the planets ...
This infant world, estimated at around 10 to 20 times the mass of Earth, is one of the youngest planets beyond our solar system - called exoplanets - ever discovered. ... It was found by NASA's ...
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.
