A 300-million-year-old planet discovered in 2014 has a temperature that can reach a scorching 4,315 C during the day, just 926 C cooler than our sun, astronomers have found. 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.
