Astronomers Discover New Type of Planet- The 'Mega-Earth'

Recently astrophysicists proclaimed that they have detected a new type of planet, a rocky world weighing 17 times as much as Earth. Theoreticians supposed such a world couldn't form because whatever so heavy would grasp hydrogen gas as it grew and convert to a Jupiter-like gas giant. This planet, however, is all solids and much greater than earlier discovered "super-Earths," making it a "Mega-Earth." Astrophysicist Xavier Dumusque of the Harvard-Smithsonian Center for Astrophysics (CfA), who directed the data examination and made the discovery, says "We were very surprised when we realized what we had found”

CfA scientist Dimitar Sasselov, administrator of the Harvard Origins of Life Initiative adds "This is the Godzilla of Earths! But unlike the movie monster, Kepler-10c has positive implications for life." The team's discovery was offered recently in a press session at a meeting of the American Astronomical Society (AAS). The brand-new mega-Earth, Kepler-10c, orbits a sun like star once every 45 days. It is situated about 560 light-years from Earth in the constellation Draco. The system also harbors a 3-Earth-mass "lava world," Kepler-10b, in a strangely fast at 20-hour of orbit.

Kepler-10c was initially detected by NASA's Kepler spacecraft. Kepler finds planets using the transit method, observing for a star that dims when a planet passes in front of it. By determining the extent of dimming, astronomers can compute the planet's physical size or diameter. Though, Kepler can't tell whether a planet is rocky or gassy.
