A Diamond World Bigger Than Earth 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.
The surface of this planet is likely covered in graphite and diamond rather than water and granite.
This is our first glimpse of a rocky world with a fundamentally different chemistry from Earth
This ‘diamond-rich super-Earth’ is likely just one example of the rich sets of discoveries that await us as we begin to explore planets around nearby stars.
