The announcement in this regard was made today by NASA at an astronomy meeting in Boston. The new planet is officially named Kepler-10c.
They believed that beyond about 10 Earth masses, a planet would hold onto so much hydrogen gas that it would turn similar to Jupiter or Saturn. The discovery of this new rocky structure sends signal that there’s several exoplanets in the space and they are thriving well.
M.I.T. planetary scientist Sara Seager said that nature will do what she wants and it has nothing to do with the Earthling theorists. She termed the finding “incredibly exciting.”
Kepler-10c orbits a star 560 light-years away in the constellation Draco and according to NASA, it is highly unlikely that it can sustain life.
This exoplanet is very close to the parent star and its surface must be very hot, which is not fit for the survival of life. The planet is 2.3 times the diameter of Earth, but its density is more than earth’s.
Dimitar Sasselov, a professor of astronomy at Harvard, said that it is still rock, but the rock is twice as dense as the rock we’re used to. The Kepler Space Telescope has discovered several planets.
