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 ...
30 planets: On October 19, it was announced that 30 new planets were discovered, all were detected by the radial velocity method. It is the most planets ever announced in a single day during the exoplanet era [clarification needed]. October 2009 now holds the most planets discovered in a month, breaking the record set in June 2002 and August ...

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 ...
51 Pegasi. 1995. First convincing exoplanet discovered around a Sun-like star. [2] While the minimum mass of HD 114762 b was high enough (11 Jupiter-masses) that it could be a brown dwarf, 51 Peg b's minimum mass meant that it almost certainly was near the mass of Jupiter. First planet discovered via transit.
Gliese 581c / ˈɡliːzə / ( Gl 581c or GJ 581c) is an exoplanet orbiting within the Gliese 581 system. It is the second planet discovered in the system and the third in order from the star. With a mass about 6.8 times that of the Earth, it is classified as a super-Earth (a category of planets with masses greater than Earth's up to ten Earth ...
Physical characteristics. Mass. 2.6 +4.1. −1.6 [2] MJ. MOA-2009-BLG-387Lb is an exoplanet in the orbit of the red dwarf MOA-2009-BLG-387L. Its discovery was announced on February 21, 2011, making it the eleventh planet discovered using gravitational microlensing. The planet is thought to be over twice the mass of Jupiter and to have an orbit ...
Discovery of Neptune. New Berlin Observatory at Linden Street, where Neptune was discovered observationally. Neptune as imaged by the Voyager 2 probe in 1989. The planet Neptune was mathematically predicted before it was directly observed. With a prediction by Urbain Le Verrier, telescopic observations confirming the existence of a major planet ...
