Scientists have discovered the hottest planet in the universe

The surface of KELT-9B reaches a temperature around 4,600 Kelvin while our Sun’s surface reaches 5,800 Kelvin.

Scientists have found one of the craziest exoplanets yet. It’s a huge gas giant not unlike our Solar System’s own Jupiter, but it travels around its star in just 1.5 days, with a surface hotter than most stars.

The planet orbits a blazing star called KELT-9, which is some 650 light-years away. It’s the first time astronomers have detected a planet near a star this hot, and it’s different from anything they’ve seen before.

For one, KELT-9b is crazy hot, as its surface reaches around 4,600 Kelvin on the day side. For comparison, the surface of our Sun is around 5,800 Kelvin, and even its closest planet Mercury only reaches a measly 700 Kelvin on the surface
