K2-141b

We're moving on to Hellworlds, and number 12 on the list.

K2141b has a core of rock, an ocean of rock, and an atmosphere of rock? Tidally locked to its star, temperatures on the daylight side soar to 3,000 K, that's 2,700 degrees Celsius, melting the surface rock into a liquid ocean and vaporizing the surface magma.

supersonic winds whip the rock vapor up into the atmosphere and all around the planet.

And when these hot clouds of rock steam hit the cold, dark backside, they condense and fall as rock hail.
