Kepler-10b is a planet the size of the earth and orbits Kepler-10 in the constellation Dragon in the northern sky. It is the first rocky planet to be discovered using the Kepler space telescope. The exoplanet is about 1.47 times the size and 3.72 times the mass of Earth and, until January 2011, was the smallest planet that could be found near another star and whose diameter could be determined using the transit method . It orbits its host star Kepler-10, the 560 light years from our solar system away, is approximately every 0.84 days at less than a 20th of the distance between Mercury and the sun . Also in the same system is Kepler-10c , a larger rocky planet that orbits the star every 45 days.

The data that led to the discovery of Kepler-10b was collected from May 2009 to January 2010.

Due to the short distance to its star, it is not in the habitable zone . Estimates of the planet's equilibrium temperature are greater than 1800 K (about 1600 ° C). Its density of about 6.46 ± 0.73 g / cm ³ (earth about 5.5 g / cm ³ ) indicates a higher metal content than earth.

The discovery of Kepler-10b is an important milestone for the Kepler program.
