Zin en onzin van wetenschappelijk onderzoekes following complex trajectories, where manoeuvres and close encounters with the planets play a deciding role in sending a spacecraft toward its target. This is why spaceflight dynamics should not be considered only a practical application of known principles, but also as a novel approach to orbital motion.

Around and around, celestial bodies which still holds today. Circles, ellipses, parabolas and hyperbolas — despite their simplicity from a geometrical point of view — represent the key to understanding the dynamical evolution of our Solar System and beyond.

Our chaotic Solar System, Henri Poincaré on the three-body problem, whereas the powerful computing tools at our disposal nowadays allow us to investigate the chaotic behaviour of complex N-body gravitationally interacting systems. In doing so, fast and slow chaotic diffusion emerge as the driving forces shaping the dynamics of our Solar System.

At the edge of the Solar System,years since the discovery of the first TNO, the population has grown sufficiently to allow preliminary characterisation from a dynamical point of view. Yet the feeling is that we are only at the beginning of a long path that will eventually lead to bridging the gap between the last of the planets and the distant Oort Cloud.
