The Planet with Lava Oceans and Rock Rain

Okay, on to the exoplanet K2-141b. This one sits about 200 light years

away from Earth. This is a big rocky lava planet orbiting close to its star. So close that a

year here is less than seven hours long. The surface is incredibly hot,

and oceans of magma are everywhere. But what's unique about this planet are the rocks.

There are rocks on the ground, in the ocean, even in the atmosphere. In the intense heat,

rocks and sodium atoms vaporize, and then they get hurled at supersonic speeds over to the

cold side of the planet, where they rain down as rocks. It would be like

standing in a landslide. Once they rain down, these rocks fall into the magma ocean, flow back,
