Kepler was a planet-hunting space telescope designed to discover Earth-size and larger planets orbiting in or near the habitable zones of their stars. Kepler surveyed our neighborhood in the Milky Way galaxy and, throughout its lifetime, observed over half a million stars, enabling the discovery of over 3,200 planets. The Kepler mission revealed that there are more planets than stars in our galaxy.
