List of hottest exoplanets. This is a list of the hottest exoplanets so far discovered, specifically those with temperatures greater than 2,500 K (2,230 °C; 4,040 °F). For comparison, the hottest planet in the Solar System is Venus, with a temperature of 737 K (464 °C; 867 °F).
Title Planet Star Data Notes Most massive The most massive planet is difficult to define due to the blurry line between planets and brown dwarfs.If the borderline is defined as the deuterium fusion threshold (roughly 13 M J at solar metallicity [16] [b]), the most massive planets are those with true mass closest to that cutoff; if planets and brown dwarfs are differentiated based on formation ...
The innermost planet, WASP-47e, is a large terrestrial planet of 6.83 Earth masses and 1.8 Earth radii; the hot Jupiter, b, is little heavier than Jupiter, but about 12.63 Earth radii; a final hot Neptune, c, is 15.2 Earth masses and 3.6 Earth radii. [34]

WASP-12b is a hot Jupiter [4] (a class of extrasolar planets) orbiting the star WASP-12, discovered in April of 2008, by the SuperWASP planetary transit survey. [5][1] The planet takes only a little over one Earth day to orbit its star, in contrast to about 365.25 days for the Earth to orbit the Sun. Its distance from the star (approximately 3. ...
Temperature. 4050 ± 180[1] K. KELT-9b is an exoplanet and ultra-hot Jupiter that orbits the late B-type /early A-type star KELT-9, [4] located about 670 light-years from Earth. [4] Detected using the Kilodegree Extremely Little Telescope, the discovery of KELT-9b was announced in 2016. [5][1] As of June 2017, it is the hottest known exoplanet.
A hot Neptune is a type of giant planet with a mass similar to that of Neptune or Uranus orbiting close to its star, normally within less than 1 AU. [1] The first hot Neptune to be discovered with certainty was Gliese 436 b (Awohali) in 2007, an exoplanet about 33 light years away. Recent observations have revealed a larger potential population ...
Venus is the second planet from the Sun. It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth. Venus has by far the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover.
