The heritage of the Kepler Space Mission: Exo-planets, Binaries and Circumbinary Planets
 
The Kepler space mission has retired last month after operating since 2009, discovering thousands of transiting planets and planet candidates. As a result, we know that exo-planets are quite frequent, many of them can be found in multiple planetary systems and some orbit binary stars.  The dynamical features of most of the detected planets are quite different from those observed in our solar system. The newly discovered population of exo-planets can help us understand the formation and evolution of planetary systems.
