'''Kepler is a NASA spacecraft equipped with a space observatory designed to discover Earth-like planets orbiting other stars.[4] The spacecraft is named in honor of German astronomer Johannes Kepler.[5] The spacecraft was launched on March 7, 2009,[6] with a planned mission lifetime of at least 3.5 years.[7] According to NASA, the Kepler Mission is "specifically designed to survey a portion of our region of the Milky Way galaxy to discover dozens of Earth-size planets in or near the habitable zone and determine how many of the billions of stars in our galaxy have such planets."[8] Kepler uses a photometer developed by NASA to continuously monitor the brightness of over 145,000[9] main sequence stars in a fixed field of view. The data collected from these observations will be analyzed to detect periodic fluctuations that indicate the presence of extrasolar planets (planets outside our solar system) that are in the process of crossing the face of other stars.
