The study of the Solar system, particularly of its newly discovered outer parts, is one of the hottest topics in modern astrophysics with great potential for revealing fundamental clues about the origin of planets and even the emergence of life. The three lecturers of the 35th Saas-Fee Advanced Course, which have been updated and collected in this volume, cover the field from observational, theoretical and numerical perspectives.
