There are 4,379 known exoplanets, or planets outside the Solar System that orbit a star, as of December 1, 2020; only a small fraction of these are located in the vicinity of the Solar System. An exoplanet or extrasolar planet is a planet outside the Solar System. An extrasolar planet (or exoplanet) is a natural planet in a planetary system outside our own solar system.. This is a list of potentially habitable exoplanets.The list is based on estimates of habitability by the Habitable Exoplanets Catalog (HEC), and data from the NASA Exoplanet Archive.The HEC is maintained by the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo.. Within 10 parsecs (32.6 light-years), there are 97 exoplanets listed as confirmed by the NASA Exoplanet Archive. Astronomers have had much better success at indirectly detecting extrasolar planets. The smaller estimate studied planet candidates gathered by the Kepler space observatory. Advantages: The Radial Velocity method was the first successful means of exoplanet detection, and has had a high success rate for identifying exoplanets in both nearby (Proxima b … The first confirmation of detection occurred in 1992. Instead of detecting the planet, they infer its existence by observing the effects that it has on its parent star. This is a list of exoplanets.As of 19 November 2020, there are 4,306 confirmed exoplanets, the majority of which were discovered by the Kepler space telescope.There are an additional 2,366 potential exoplanets from Kepler's first mission yet to be confirmed, as well as 889 from its "Second Light" mission and 1,445 from the Transiting Exoplanet Survey Satellite (TESS) mission. It is the first planet with a radius similar to Earth's to be discovered in the habitable zone of another star. In 2013, estimates of the number of terrestrial planets in the Milky Way ranged from at least 17 billion to at least 144 billion. 7 oktober 2020 fanns det registrerat 4 284 planeter i 3 179 solsystem. Kepler-186f (also known by its Kepler object of interest designation KOI-571.05) is an exoplanet orbiting the red dwarf Kepler-186, about 500 light-years (178.5 parsecs, or nearly 5.0 × 10 15 km) from the Earth. En astronomie, la recherche des exoplanètes fait appel à plusieurs méthodes de détection.La majorité de ces méthodes sont à l'heure actuelle indirectes, puisque la proximité de ces planètes avec leur étoile est si grande que leur lumière est complètement noyée dans celle de l'étoile. This was followed by the confirmation of a different planet, originally detected in 1988. The first possible evidence of an exoplanet was noted in 1917, but was not recognized as such. Exoplanet Exploration Program NASA's science, technology and mission management office for the exploration of exoplanets. Die größten Objekte sind selbst Braune Zwerge. Ein Exoplanet, auch extrasolarer Planet, ist ein planetarer Himmelskörper außerhalb (griechisch ἔξω) des vorherrschenden gravitativen Einflusses der Sonne, aber innerhalb des gravitativen Einflusses eines anderen Sterns oder Braunen Zwergs.Extrasolare Planeten gehören also nicht dem Sonnensystem, sondern anderen Planetensystemen an. En extrasolär planet, eller exoplanet, är en planet som befinner sig utanför vårt eget solsystem.De första upptäckterna gjordes under 1990-talet. The program's primary goals, as described in the 2014 NASA Science Plan, are to discover planets around other stars, to characterize their properties and to identify planets that could harbor life. Thus, extrasolar planets are simply too near their much brighter parent stars to be directly imaged from interstellar distances. O planetă extrasolară (exoplanetă) deosebită este Gliese 581 c, care a fost descoperită în aprilie 2007 la Observatorul astronomic din Geneva: ea prezintă temperaturi de suprafață între 0 și 40 °C.Ca urmare, dacă acolo ar exista apă, atunci ea s-ar afla în stare lichidă, îndeplinind astfel măcar una dintre condițiile necesare pentru existența vieții extraterestre.
