"This is the first evidence of a rocky planet that is fundamentally have different chemical composition to Earth. Surface of the planet is mostly covered with graphite and diamonds than water and granite," said Nikku Madhusudhan, astronomer discoverer.
Yale University astronomer discovered a planet rich in diamonds. The planet is twice the size of Earth, orbiting the Sun-like star and neighbors.
“This is the first evidence of a rocky planet that is fundamentally have different chemical composition to Earth. Surface of the planet is mostly covered with graphite and diamonds than water and granite,” said Nikku Madhusudhan, astronomer discoverer.
The diamond planet called 55 Cancri e, has 8 times the mass of Earth’s so-called super-Earth planet. This planet is one of the five planets that orbit 55 Cancri star, located 40 light-years from Earth.
Is the human habitable planet?
55 Cancri e orbits at high speed. One year on the planet is equal to 18 hours on Earth. Temperature of the planet is also very hot, reaching 2149 degrees celsius.
Astronomers suspect that 55 Cancri e has a super hot water. However, observations show that the planet has no water at all. The composition of the majority of the planet’s only carbon, iron, silicon, and silicates. Diamond content of 75 percent.
Thus, the new planet is not habitable. Living in the diamond-rich planet is just going to be a dream.
This discovery, says Madhusudhan, showed that carbon-rich super-Earth planet that can no longer be assumed far have compositions similar to Earth. These findings also open up opportunities in other studies, reveal the influence of the composition of the planet in volcanic and tectonic activity.
“Super-Earth is rich in diamonds is one of the discoveries that await us to explore neighboring planets orbiting the Sun,” said Madhusudhan Physorg quoted on Thursday (10/11/2012). Research to be published in the Astrophysical Journal Letters.
