KELT-9b: The Hottest Known Exoplanet

Kelt-9b is a gas giant planet that orbits a star 670 light-years from Earth. It is so close to its star that its dayside temperature is 7,800 degrees Fahrenheit (4,300 degrees Celsius), hotter than some stars. This heat is so intense that it rips apart the molecules in the planet's atmosphere, including hydrogen gas.
