For three centuries astronomers and mathematicians have studied the problem of the solar system stability. The high analytical complexity of this issue prevented some advances that could only be achieved with the advent of computers and current numerical techniques. The dynamic evolution of the solar system is classified as chaotic. But the long age of stability of the Solar System suggests that, despite the chaos, the system tends to avoid dynamic instabilities and search for conditions of stability. The Nice model deals with the dynamical evolution of the solar system from the formation of planets to the current settings and explains phenomena and settings found in astronomical observations. Furthermore, the Nice model achieved a stable configuration for the solar system for a long period of time. However, the Nice model treats only with the dynamics of the giant planets of the Solar System and the planetesimal disk. The purpose of this project is to include the main three inner planets of the solar system using the initial conditions of the Nice model and check the stability of this new dynamical system featuring its chaotic level.
