Abstract

The dynamical structure of the orbital element space of the Pluto-Charon system is studied in the model of the spatial circular restricted three-body problem by using numerical methods. With the two newly discovered small satellites S/2005 P1 and S/2005 P2, the Pluto-Charon system can be considered as the first known binary system in which celestial bodies move in P-type orbits. It is shown that the two satellites are in the stable region of the orbital element space and their origin by capture is unlikely. Also the large mass parameter allows the satellites to be regarded as a model of a new class of exoplanets orbiting around stellar binary systems.
