The planet, called 55 Cancri e, has a radius twice as big as Earth’s and a mass eight times greater. It is one of five planets that orbit a star 40 light years from Earth.
“This is our first glimpse of a world with a fundamentally different chemistry from Earth,” said lead researcher Nikku Madhusudhan, a Yale postdoctoral researcher in physics and astronomy.
“The surface of this planet is likely covered in graphite and diamond rather than water and granite.”
The planet orbits exceedingly quickly. Its year lasts just 18 hours, in contrast to Earth’s 365 days. Researchers say it is also blazingly hot, with a temperature of about 2,149 C — a far cry from a habitable world.

I can imagine there are some who would like to get their hands on this planet.
