A new plane found called (Mega-Earth)

Many of you do not know there is a new planet found in our universe far from earth. It is calles the Mega Earth. But it's original name is  Kepler-10c. we are going to know a short thing about this planet in the content below:                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            It is associate degree object with a tough surface like our own world however abundant, abundant larger.

The necessity for the new designation follows the invention of a planet that encompasses a mass some seventeen times that of Earth.

Known as Kepler-10c, it orbits a star concerning 560 light-years away. Scientists represented its properties at associate degree yank Astronomical Society meeting in Boston.

They confess it's one thing of a head-scratcher.

Theorists had continuously thought that any planet that enormous would pull such a lot chemical element on to itself that it might look a lot of sort of a Neptune or a Jupiter.

"The correct thanks to decision it's one thing larger than a 'super-Earth, thus however concerning 'mega-Earth," academic Dimitar Sasselov, of the Harvard-Smithsonian Center for astronomy (CfA), told reporters. He conjointly used the phrase, "the Godzilla of Earths!".                                                                                                                                                                                                            

Double probe

Kepler-10c, because the name suggests, was detected by the North American nation area agency's Johan Kepler telescope.

This finds new worlds by searching for the little dip in light-weight as they pass ahead of their parent stars.

The technique provides a diameter - during this case, 29,000km, or simply over double the breadth of Earth - however not a mass.

For that, astronomers checked out 10c with the Harps-North instrument on the Telescopio Nazionale astronomer within the Canaries.

It extracts a mass measuring by examining the fundamental interaction between the earth and its host star.

Combined with the diameter, the mass unit showed that Kepler-10c can't be a vaporific world however should comprise terribly dense material.                                                                                                

                                                        

Life hunt

"It's seventeen - really, it's over seventeen - Earth lots, which brings the density to seven.5 grams per milliliter, that may be a ton over what we all know of rock here on Earth (5.5g/cm3)," aforesaid academic Sasselov.

"But bear in mind, this is often a really huge planet, which suggests those self same minerals square measure extremely compressed.

"So, what you see within the density is usually thanks to compression instead of totally different composition. The composition comes out as being a mix of rocks and a few volatiles, most likely 5-15% at the most of water."

The discovery adds to our understanding of the combination of planet sorts we have a tendency to currently understand square measure out there, and tells North American nation one thing new concerning once rocky worlds would possibly transition to vaporific planets in their youth.

Interestingly, the age of the host star is concerning eleven billion years previous, that is early within the evolution of the Universe once generations of exploding stars haven't had long to create the serious parts required to construct rocky planets.

So, Kepler-10c's properties counsel rocky planets might have fashioned earlier in cosmic history than several thought potential, which terribly previous star systems shouldn't be neglected within the rummage around for life on the far side Earth.

"It is [on] solid planets that's the place, as way as we all know - and that we little or no concerning the origins of life - wherever we expect the chemistry is capable of building those molecules that result in the emergence of life from chemistry," says academic Sasselov.                                                                                                                                                                                                           leave our commen below
