Kepler has also measured the reflected light from some planets already known, discovering planets undetectable with the transit method [15] as well as improving knowledge of the characteristics of planets already discovered. [16] On February 26, 2014, NASA announced the discovery of 715 newly verified exoplanets around 305 stars by the Kepler ...
Seven Earth-sized planets have been discovered orbiting a nearby star, three of which appear to be warm enough to sustain life, according to astronomers from NASA and the European Southern ...
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 ...

On 15 April 2019, TESS' first discovery of an earth-sized planet was reported. HD 21749 c is a planet described as "likely rocky", with about 89% of Earth's diameter and orbits the K-type main sequence star HD 21749 in about 8 days. The planet's surface temperature is estimated to be as high as 427 °C.
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away.. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
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 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.
