Determining which small exoplanets have stony-iron compositions is necessary for quantifying the occurrence of such planets and for understanding the physics of planet formation. Kepler-10 hosts the ...

A new planetary member of the Kepler-10 solar system was announced today. Using data from NASA’s Spitzer Space Telescope, members of the Kepler science team confirmed a new planet, dubbed Kepler-10c.

The Kepler-10 planetary system is clearly a place of extremes. It has a small, Earth-sized world that is half scorched, the first rocky world ever discovered by the Kepler mission. That’s Kepler-10 b.

NASA’s Kepler mission confirmed the discovery of its first rocky planet, named Kepler-10b. Measuring 1.4 times the size of Earth, it is the smallest planet ever discovered outside our solar system.

Just like that we have 219 new exoplanet candidates of which 10 are near-Earth size and orbiting in the habitable zone of their host suns. That's the latest haul from the Kepler space telescope team.
