The young planet, KELT-9b, is about 650 light-years away and is 2.8 times more massive than Jupiter, but only half as dense. The planet's intense heat comes from its star, KELT-9, that is more than twice as large as our sun and nearly twice as hot. As the star produces such intense radiation, the day side of planet's atmosphere would be stripped down to individual atoms. As the intense UV blasts the planet, it could be throwing some of the evaporated material into space as the planet orbits, sort of like a comet, the researchers said. In about a million years, the star will swell and become a red giant, which would consume the planet if it is still around.
