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 exoplanets irradiated by a nearby star and greater than 2,000 K (1,730 °C; 3,140 °F) for self-luminous exoplanets.
Gliese 436 b / ˈ ɡ l iː z ə / (sometimes called GJ 436 b, [7] formally named Awohali [2]) is a Neptune-sized exoplanet orbiting the red dwarf Gliese 436. [1] It was the first hot Neptune discovered with certainty (in 2007) and was among the smallest-known transiting planets in mass and radius, until the much smaller Kepler exoplanet discoveries began circa 2010.
51 Pegasi b: In 1995 this became the first exoplanet orbiting a main-sequence star to have its existence confirmed.It is a hot Jupiter with a 4.2-day orbit. [12]47 Ursae Majoris b: In 1996 this Jupiter-like planet was the first long-period planet discovered, orbiting at 2.11 AU from the star with the eccentricity of 0.049.
It was the first exoplanet to be discovered orbiting a main-sequence star, [3] the Sun-like 51 Pegasi, and marked a breakthrough in astronomical research. It is the prototype for a class of planets called hot Jupiters. [4] In 2017, traces of water were discovered in the planet's atmosphere. [5]
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]
Daytime temperatures on KELT-9b can reach up to 7,800 degrees Fahrenheit -- to put that in perspective, our own sun's surface temperature is only 9,941 F.
WASP-193b is a hot, transiting gas giant planet located approximately 1,232 light-years (378 pc) away [4] in the constellation of Hydra, orbiting the F-type star WASP-193. Its discovery was made by the WASP-South transit survey and announced in 2023.
HD 189733 b is an exoplanet in the constellation of Vulpecula approximately 64.5 light-years (19.8 parsecs) away [7] from the Solar System.Astronomers in France discovered the planet orbiting the star HD 189733 on October 5, 2005, by observing its transit across the star's face. [1]
