Kelt-9b

KELT-9b - a planet found using the Kilodegree Extremely Little Telescope, or KELT - is hotter than most stars with a dayside temperature of more than 4,300 degrees Celsius.

The hottest planet ever discovered orbits a massive star so sizzling it burns bluish white. On exoplanet KELT-9b, a gas giant 650 light-years from Earth, temperatures during the day reach 4,300 degrees Celsius, or 7,770 degrees Fahrenheit. That's only about 1,300 degrees Celsius cooler than the surface of the sun. Venus, the planet in our solar sys...
