Shimmering "super earth" in the constellation discovered Cassiopeia



LONDON Scientists have discovered a new exotic planet outside our solar system in the Cassiopeia constellation.

Located 21 light years away from us, this planet, dubbed HD219134 b, has a mass almost five times that of the earth which is considered a so-called "super earth".

Unlike the earth, it probably does not have a solid core of iron, but is rich in calcium and aluminum along with magnesium and silicon.

"Therefore, such planets cannot, for example, have a magnetic field like the earth," says one of the researchers Caroline Dorn, astrophysicist at the Zurich University in Switzerland.

And since the inner structure is so different, their cooling behavior and atmospheres will also differ from the usual super Earth.

"Perhaps it shimmers red to blue like rubies and sapphires, for these gemstones are aluminum oxides common to the exoplanet," Dorn said.

9134 b is one of three candidates likely to belong to a new exotic class of exoplanets, the researchers said, according to the study published in the Monthly Notices magazine of the Royal Astronomical Society: Letters.

The other two exoplanets studied, 55 Cancri e and WASP-47 e, pave their star so close that their surface temperature is nearly 3000 degrees.

"So we have found three candidates belonging to a new class of super earth with this exotic composition," the researchers said.
