A Diamond planet Planet PSR J1719-1438 b, located far outside our solar system, is composed largely of crystalline carbon, the same material found in diamonds. This planet likely formed from a ...
Another, named PSR J1719-1438 b, is believed to be made entirely out of crystal diamond. A member of a Jupiter class of planets that orbit very close to their stars — “hot Jupiters” — is ...
This planet is paired with pulsar PSR J1719-1438 and scientists think it is entirely made of carbon so dense that it must be crystalline, meaning a large part of the world would be diamond.
