According to scientists, the recently discovered exoplanet known as COROT-7b is so close to its primary that it rains molten rock:
To find out what COROT-7b’s atmosphere might be like, Fegley and his colleagues modeled it. They found that COROT-7b’s atmosphere is made up of the ingredients of rocks and when “a front moves in,” pebbles condense out of the air and rain into lakes of molten lava below.
“Sodium, potassium, silicon monoxide and then oxygen — either atomic or molecular oxygen — make up most of the atmosphere,” Fegley said. But there are also smaller amounts of the other elements found in silicate rock, such as magnesium, aluminum, calcium and iron.
The rock rains form similarly to Earth’s watery weather: “As you go higher the atmosphere gets cooler and eventually you get saturated with different types of ‘rock’ the way you get saturated with water in the atmosphere of Earth,” Fegley explained. “But instead of a water cloud forming and then raining water droplets, you get a ‘rock cloud’ forming and it starts raining out little pebbles of different types of rock.”
It’d make hell seem like a holiday cottage in the Poconos.
