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.
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] 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.
Hottest non-compact star with a planet NSVS 14256825 b: NSVS 14256825: 40 000 K (primary) [108] NN Serpentis is hotter, with a temperature of 57 000 K for the primary star, [1] but the existence of its planets is disputed. [109] A candidate planet was found around the O-type subdwarf TOI-709, whose effective temperature is higher at 50,000 K. [110]
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.
The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk. There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets.
Beginning in June, the planet notched month after month of warmer-than-usual conditions, with July and August 2023 coming in as the warmest two months ever recorded, according to the Copernicus ...
K2-18b, also known as EPIC 201912552 b, is an exoplanet orbiting the red dwarf K2-18, located 124 light-years (38 pc) away from Earth.The planet is a sub-Neptune about 2.6 times the radius of Earth, with a 33-day orbit within the star's habitable zone.
The planet is what’s known as a gas giant, which means it doesn’t have a solid surface — though it may have a solid core about the size of the Earth. ... USA TODAY is exploring the questions ...
