Hmm If this is true then we are definitely talking about a planet that is made up of diamonds because what else could be bigger than Earth.
A planet twice the size of our own made largely out of diamond has been discovered. The rocky planet, called ’55 Cancri e’, orbits a sun-like star in the constellation of Cancer and is moving so fast that a year there lasts a mere 18 hours.
It is also incredibly hotter, larger and bigger than Earth. This planet is also called Super earth.
