London: A new ‘Super Earth’, an exotic planet has been discovered by Researchers, outside our solar system in the Cassiopeia Constellation which is located 21 light years away from earth.
This planet dubbed HD219134 b, has a mass almost five times that of Earth, but does not have a massive core of Iron as it is rich in calcium and aluminium with magnesium and silicon.
One of the researchers Caroline Dorn, astrophysicist at the University of Zurich in Switzerland, said “This is why such planets cannot have a magnetic field like Earth, and because the inner structure is so different, their cooling behaviour and atmospheres will also differ from those of normal super-Earths.”
“The red and blue colour of the super Earth, like that of rubies and sapphires, is due to the presence of aluminium on it”
The HD219134 b is one of the three exoplanets which belongs to the new exotic class, said the researchers, according to the study published in the journal Monthly Notices of the Royal Astronomical society.
The other two are 55 Cancri e and WASP-47 e, orbit their star so closely that their surface temperature is almost 3000 degrees.
