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.
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.
51 Pegasi b, officially named Dimidium / d ɪ ˈ m ɪ d i ə m /, is an extrasolar planet approximately 50 light-years (15 parsecs) away in the constellation of Pegasus.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.
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.
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-39b, officially named Bocaprins, is a "hot Jupiter" extrasolar planet discovered in February 2011 [3] by the WASP project, notable for containing a substantial amount of water in its atmosphere. [ 1 ] [ 4 ] [ 5 ] In addition WASP-39b was the first exoplanet found to contain carbon dioxide in its atmosphere, [ 6 ] [ 7 ] and likewise for ...
Host star is the brightest star with multiple known transiting Earth-size exoplanets. Another transiting planet in the system is suspected.

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]
