A group of American and French astronomers discovered a planet whose surface consists mainly of graphite and diamond.Which called 55 Cancri e, orbits the star, which is visible to the naked eye. It is located 40 light-years away in the constellation of Cancer.
The planet orbits the star so quickly that year it takes less than 18 hours.
Density of 55 Cancri e is 8 times greater than the density of the Earth. Surface temperature reaches 1650 degrees Celsius. According to astronomer Oliver Mosisili from the Institute of Astrophysics and Planetary Science at Toulouse, a third of the planet's mass, and the mass of the earth is three, are diamonds.
Diamond planet scientists have found in the past, but this is the first time that such a planet has been discovered near the sun-like star.
