Mesurer le chaos dans le système solaire simplifié

Abstract

Human has always been interested in astronomy. Useful for planning the year, it also exerts a deep fascination for him. In antiquity, the stars have received the names of the gods ... As for the Gauls, they had only one fear: that the sky is falling on their head ! Is this a possibility ? The Universe, and more specifically the Solar System, will be always regular ? Could we deal with collisions between planets ? The tragic end of the dinosaurs could repeat itself in the era of humans ? This thesis aims to stimulate further thoughts and solutions to the stability, regularity of the Solar System. It represents some of the tools available for the human race to describe, analyze, understand and predict celestial events of the universe and especially the Earth and the other planets orbiting around the same Sun.
