There may be a planet made out of diamonds. As space facts go, this is pretty impressive. Research by Yale University scientists suggests that a rocky planet called 55 Cancri e — which has a radius twice Earth’s, and a mass eight times greater – may have a surface made up of graphite and diamond. It’s 40 light years away but visible to the naked eye in the constellation of Cancer.
