An alien world where it rains rocks!!!

On Earth, strange things, including frogs and fish, sometimes fall from the sky, but on a distant extrasolar planet, the weather could be even weirder: When a front moves in, small rocks rain down on the surface, a new study suggests.

The exoplanet, COROT-7b, was discovered in February by the COROT space telescope launched by the French and European space agencies. Last month is became the first planet outside our solar system to be confirmed as a rocky body — most other known exoplanets are gas giants.

The planet is nearly twice the size of Earth and about five times the mass of our world. Calculations have indicated it has a density about that of Earth's, which means it is likely made up of silicate rocks, just as Earth's crust is.


The planet is likely much less hospitable to life though, as it is only about 1.6 million miles (2.6 million km) away from its parent star — 23 times closer than Mercury sits to the sun.
