Exoplanet: Kepler-10b Description The first rocky planet to be discovered by NASA's Kepler Mission, Kepler-10b is an exoplanet 1.4 times the size of our Earth. An exoplanet is any identified planet outside of our own Solar System. As of June 2013, there have been 866 exoplanets identified, located around 671 stars, nearly all within the Milky Way Galaxy. Kepler-10b has a density 4.6 times that of Earth, or similar to an iron dumbbell.
Johannes Kepler studied the orbits of the planets and found that the time period of a planet's orbit squared in years is equal to the distance from the sun cubed in AU (that is, astronomical units, or the distance from the Earth to the sun): So Earth has an orbital period of one year, so is 1 AU from the sun. Mars has an orbital period of 1.88 years (these orbital periods had been known since ancient times by observation) and so it's distance from the sun is:
