Planet Hell

Hot rocks rain from the sky, and oceans of lava ooze across one side while sunlight never shines on the other. Welcome to Hell, aka, the alien planet CoRoT-7b. Initially described in 2009, the weird world was the first rocky planet found outside our solar system.

But unlike Earth, CoRoT-7b orbits just 1.5 million miles (2.5 million kilometers) away from its star—about 23 times closer than Mercury is to our sun. The planet is also tidally locked, so that one side always faces the star while the other side lies in constant darkness.

Astronomers calculate that the surface of the star-facing side is a broiling 4,220 degrees Fahrenheit (2,327 degrees Celsius).
