Planets in Systems from NASA’s Kepler Mission

The image above depicts multiple planet systems discovered by NASA’s Kepler mission and confirmed by transit timing variations (as of January 2012). Out of hundreds of candidate planetary systems, scientists had previously verified six systems with multiple transiting planets (denoted here in red). Now, Kepler observations have verified planets (shown here in green) in 11 new planetary systems. Many of these systems contain additional planet candidates that are yet to be verified (shown here in dark purple). For reference, the eight planets of the solar system are shown in blue.
