# SIMBa: Sympletic Methods for Long-Term Integration of the Solar System

El proper dilluns, 22 d’abril, se celebrarà una nova sessió del Seminari Informal de Matemàtiques de Barcelona (SIMBa).

To model the Solar System dynamics we use the N-Body problem as a ‘toy model’. We will show that for the planetary case, using an appropriate set of coordinates, the equations of motion are written as an integrable part, $H_A$, that corresponds to the Keplerian motion of each planet around the Sun and a small perturbation, $H_B$, given by the interaction of the planets between each other. The integration of the system is done using a class of splitting symplectic methods that take into account the structure of this Hamiltonian system ($H = H_A + \epsilon H_B$).
