The book contains materials on the history of the discovery and study of minor planets, observation methods, calculations of orbits and ephemeris, issues of planetary dynamics, origin and physical structure, as well as statistical data. In the chapters devoted to observation methods, determination and improvement of orbits, numerical methods of celestial mechanics, analytical methods of perturbation theory, in addition to general acquaintance with the subject, specific methods and computational schemes for practical use are given. The publication can be used as a reference.
