There is an exoplanet discovered by the Kepler space telescope, called the planet of hell. But why do everyone call it that, and what's so special about it? Well, you'll find out here.

This planet of hell is called K2-141b (or EPIC 246393474.01) and was discovered by NASA in 2018. The exoplanet is of the Super Earth type with a mass of 5.08 x Earths mass and a radius of 1.51 x Earth radius.

Researchers believe that this planet could be a potential rocky world, and the chances of an alien life there are almost impossible, being so close to its star (K2-141). K2-141b completes an orbit around K2-141 in 0.3 days! This is one of the shortest orbital periods ever discovered on an exoplanet.

Well, it is called the planet of hell because the oceans on it, if you can believe it, may have volcanoes in them, and it is believed that the main thing flowing through its oceans is magma.

If so far we are not convinced that it is the planet of hell, well, it will scare you to know that the temperatures are so high that even the magma evaporates from the oceans.

When magma evaporates, it logically forms some mineral vapors that are carried to the cold part of the exoplanet, ie where it is night, by supersonic winds, which reach speeds of 1.75 km/s. And then, when they got there, it's kind of a strangely rain in another ocean of magma.

After all this circuit, the currents carry everything that the winds have brought, back to the hot part of the exoplanet (where it is day), where it evaporates again and the cycle begins again.

Temperatures there reach around 3000 K, but scientists believe the temperatures could be much higher. During which approx. two-thirds of the exoplanet is exposed to daylight, the other third is facing very cold temperatures of 73.15 K.

So, even if it's a Super Earth, we don't think we'd want to get there.
