The list of exoplanets detected by the ''Kepler'' spacecraft contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type. , the ''Kepler'' spacecraft and its follow-up observations have detected 1,000 confirmed planets, including hot Jupiters, super-Earths, circumbinary planets, and planets located in the circumstellar habitable zones of their host stars. In addition, ''Kepler'' has detected over 3,601 unconfirmed planet candidates〔(【引用サイトリンク】url=http://www.nasa.gov/mission_pages/kepler/main/index.html )〕 and 2,165 eclipsing binary stars.〔 In addition to detecting planets itself, ''Kepler'' has also uncovered the properties of three previously known extrasolar planets. Public ''Kepler'' data has also been used by groups independent of NASA, such as the Planet Hunters citizen-science project, to detect several planets orbiting stars collectively known as Kepler Objects of Interest.〔 ''Kepler'', launched on March 7, 2009, was designed to observe a fixed portion of the sky in visible light and measure the light curves of the various stars in its field of view, looking for planets crossing in front of their host stars via the transit method. Since the launch of the spacecraft, though, both the ''Kepler'' team at NASA and independent researchers have found new ways of detecting planets, including the use of the transit timing variation method and relativistic beaming. In addition, gravitational microlensing has been proposed as a method of using ''Kepler'' to detect compact objects, such as white dwarfs, neutron stars, and black holes.〔 ''Kepler'' has also measured the reflected light from some planets already known, discovering planets undetectable with the transit method as well as improving knowledge of the characteristics of planets already discovered. 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 size of Earth and were in habitable zones where surface temperatures are suitable for liquid water. ==Table== All planets discovered lie in one of the three northern constellations of Cygnus, Lyra and Draco, which contain Kepler's photometer's field of view. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「List of exoplanets discovered using the Kepler spacecraft」の詳細全文を読む スポンサード リンク
