Planet found where it hails real stones.

The COROT space telescope has detected a planet about 489 light years away where it apparently rains rocks.  The planet is the first known rocky planet outside our solar system, about twice the size of Earth.  Previously discovered extrasolar planets have all been gas giants.  COROT-7b is only 1.6 million miles away from its orange dwarf star, COROT-7, and gravitationally locked.  The heat from the star vaporizes the rock surface of the locked face, and the vapor forms clouds of rock that drift in the atmosphere to the cooler side of the planet and precipitate as stones and pebbles.  The star and planet are in the Monoceros constellation.
