The objective of this course is to introduce general principles of planet formation, dynamics of the solar system and recent scientific progress in extra-solar planet search. The course material will be covered in three modules: 1) Formation of planetary systems: general properties of a planetary system, protoplenetary disks, formation of the central star, formation and growth of planetesimals, evolution of planetary systems. 2) The solar system: general and dynamical properties of our solar system, fundamental characteristics of the major members; the Sun, eight planets and dwarf planets. 3) Extrasolar planets: a short history of their discovery, detection techniques and observational biases, their physical properties, their implications and future prospects, formation of life forms on a distant planet.
