The origin of chaos in the Solar System through computer algebra

The discovery of the chaotic motion planets in Solar System dates back more than 30 years. Still, no analytical theory has satisfactorily addressed origin chaos so far. Implementing canonical perturbation computer algebra system TRIP, we systematically retrieve secular resonances at work along orbital solution a forced long-term dynamics inner planets. We compare time statistic their half-widths to ensemble distribution maximum Lyapunov exponent and establish dynamical sources an unbiased way.
