Forget fiery wastelands, K2-18c is a true inferno, where temperatures soar hot enough to melt lead. This scorching exoplanet wouldn't just roast you, it would vaporize you instantly. No wonder they call it "hell."
K2-18c is also called Abaddon, which is a Hebrew word meaning "place of destruction," because of its scorching temperatures that could instantly vaporize anything that comes close.
