Stars are at least hotter than planets,right? Well, not if we talk about the newly discover gas giant KELT-9b 
This newly discovered Jupiter-like world is so hot that it’s stretching the definition of the word “planet.”
With a day-side temperature of 4,600 Kelvin (more than 7,800 degrees Fahrenheit/4,300 degrees  centigrade), planet KELT-9b is hotter than most stars, That not only makes it the hottest gas giant ever found, but makes it rival the heat of our own sun (5,500 degrees centigrade. isn't far off). In fact, it's actually hotter than some stars: red dwarfs can be as cool as 2,300 degrees  centigrade.
KELT-9b orbits a star, dubbed KELT-9, which is more than twice as large and nearly twice as hot as our sun.
“It’s a planet by any of the typical definitions based on mass, but its atmosphere is almost certainly unlike any other planet we’ve ever seen just because of the temperature of its day side,” said Scott Gaudi, professor of astronomy at The Ohio State University and a leader of the study.  

Keivan Stassun, a professor of physics and astronomy at Vanderbilt who directed the study with Gaudi said, “KELT-9 radiates so much ultraviolet radiation that it may completely evaporate the planet. Or, if gas giant planets like KELT-9b possess solid rocky cores as some theories suggest, the planet may be boiled down to a barren rock, like Mercury.”
