This chapter is a review of the dynamics of two-planet systems. It includes the study of averaged models of both secular and resonant planetary configurations. The introduction describes our understanding of long-term planetary behavior and stability. The next section introduces the presently known sample of 31 extra-solar systems and the classification of these systems with respect to their dynamical behavior. Their secular dynamics are described in Section 3, where we also introduce the main techniques commonly used for exploring dynamical features. We conclude this section by describing the effects of the proximity of a secular system to mean-motion resonances. Finally, phenomena related to mean-motion resonances are presented in Section 4.
