breaks new records

A small planet 500 light years away has been found to be the fastest moving planet known, whizzing around its star once every 20.4 hours. To orbit so quickly the planet, known as CoRoT-7b, must be only 2.5 million kilometres from its sun. It is the first planet to be unambiguously confirmed as a rocky planet.
