Résumé :

Modern problems of the dynamics of exoplanetary systems are considered. Types and characteristics of the dynamical structure of planetary systems of single and binary stars are discussed, and examples of remarkable planetary systems are provided, demonstrating their similarities and differences with respect to our Solar system. Particular attention is paid to chaotic clearing effects arising due to interaction of orbital resonances.
