Kepler-10 is a star in a Draco constellation, 560 light years away from our Solar System. The age of the star is estimated to be approximately 11.9 billions of years.[citation needed] The only known member of the star's planetary system, Kepler-10b, is of particular interest because of its rocky nature and little, nearly Earth-like size. A second planet, Kepler-10c, is unconfirmed.
