The currently preferred radius estimate is done by SED modelling including substellar object and disk model. [ 9] Ditsö̀ (WASP-17b) 1.991 ± 0.081 [ 31] 0.486 MJ; has an extremely low density of 0.08 g/cm 3. [ 32] Possibly largest exoplanet at the time of discovery. [ 33] Kepler-435b.
TrES-4b. TrES-4b is an extrasolar planet, and one of the largest exoplanets ever found. It was discovered in 2006, and announced in 2007, by the Trans-Atlantic Exoplanet Survey, using the transit method. It is approximately 1,400 light-years (430 pc) away orbiting the star GSC 02620-00648, in the constellation Hercules. [1]
List of nearest exoplanets. Fomalhaut b (Dagon), 25 light-years away, with its parent star Fomalhaut blacked out, as pictured by Hubble in 2012. [ 1] In 2020 this object was determined to be an expanding debris cloud from a collision of asteroids rather than a planet. [ 2] There are 7,026 known exoplanets, or planets outside the Solar System ...
Proxima Centauri b is the closest exoplanet to Earth, [20] at a distance of about 4.2 ly (1.3 parsecs). [5] It orbits Proxima Centauri every 11.186 Earth days at a distance of about 0.049 AU, [1] over 20 times closer to Proxima Centauri than Earth is to the Sun. [21] As of 2021, it is unclear whether it has an eccentricity [e] [24] but Proxima Centauri b is unlikely to have any obliquity. [25]
A Super-Earth is a type of exoplanet with a mass higher than Earth 's, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17 times Earth's, respectively. [1] The term "super-Earth" refers only to the mass of the planet, and so does not imply anything about the surface conditions or habitability.
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [3] [4] based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
The stars with the most confirmed planets are the Sun (the Solar System's star) and Kepler-90, with 8 confirmed planets each, followed by TRAPPIST-1 with 7 planets. The 1007 multiplanetary systems are listed below according to the star's distance from Earth. Proxima Centauri, the closest star to the Solar System, has three planets ( b, c and d ).
The Extrasolar Planets Encyclopaedia (also known as Encyclopaedia of exoplanetary systems and Catalogue of Exoplanets) is an astronomy website, founded in Paris, France at the Meudon Observatory by Jean Schneider in February 1995, which maintains a database of all the currently known and candidate extrasolar planets, with individual pages for ...
