3. Planet Of Burning Ice
GLIESE 436B is made entirely of ice. It is found in the same solar system as GLIESE 581C. But the planet is heated up to 439 degree celsius. Which technically makes the planet like burning ice cube. But the ice does not melt as the enormous amount of water is held solid by the gravity of the planet which pulls all water molecules to its core and not making it evaporate !!
