Pluto Strikes Back!

Together with its four small satellites, the Pluto-Charon binary planet provides fascinating insights into the origin and early evolution of the solar system. It is also an interesting testbed for theories of circumbinary planet formation. After describing the system architecture as revealed by HST [Hubble Space Telescope] and New Horizons, I will summarize a suite of numerical simulations designed to constrain satellite masses and to test models for satellite formation.
