PLUTO AND CHARON "KISS-AND-CAPTURE" (IMAGE) Southwest Research Institute Caption Using advanced models, SwRI led new research that indicates that the formation of Pluto and Charon may parallel that of the Earth-Moon system. In the resulting “kiss-and-capture” regime, Pluto and Charon collide and stick together in the shape of a snowman. They rotate as one body until Pluto pushes Charon out into a stable orbit.
