The article deals with the issues of teaching the topic "Solar system" of the discipline "Astronomy". The old textbook "Astronomy" by E.P. Levina and new - B.A. Vorontsova-Velyaminova, E.K. Strout and V.M. Charugin - in which the material about the planetary system is borrowed from publications of the last century. At present, what is stated in the textbook by B.A. Vorontsova-Velyaminov and E.K. Strout, the historically established idea of the formation and structure of the solar system (from planets alone) contradicts new discoveries and the observed harmonious structure of the solar system. The erroneousness of assigning the status of "minor planet" to asteroids of the main belt and many objects of the Kuiper belt is substantiated. this leads students to the misconception that there are many planets in the solar system. To the textbook "Astronomy" V.M. Charugin, the author of this article prepared a textbook "The Solar System of the 21st Century", which provides a model of the structure of the entire Solar System and the cometary hypothesis of its origin. The textbook contains a table "Periodic system of celestial bodies of the entire solar system" for astronomy classrooms, similar in significance to the table "Periodic system of chemical elements of D.I. Mendeleev.
