The small bodies of the solar system (MTSS) are comets, asteroids, centaurs, meteoroids and potentially dangerous objects for the Earth. The goal of the work. Observations of the MTSS, analysis of the results and on their basis the study of the physical state and chemical composition of bodies of different dynamic classes; identification of dynamic relationships between different populations of MTSS by studying their orbital evolution; development of theoretical and numerical modeling of physical and dynamic processes in small bodies. Research methods: surface photometry, spectroscopy, polarimetry, physical modeling. Results and their novelty. A large array of photometric, polarimetric, spectral and astrometric data for 63 comets, 52 asteroids, 9 satellites of planets and 2 centaurs on various telescopes around the world and JSC KNU. A large number of images and spectra of meteors of the Perseid meteor shower were obtained in August 2019. The possible chemical composition of the dust of the first interstellar comet 2I / Borisov was established, which was the first such determination. An explanation of the rapid changes in the color of comets is proposed. Based on complex observations of distant comets, in particular C / 2014 A4 (SONEAR) and C / 2011 KP36 (Spacewatch), it was found that dust in distant comets differs from dust in nearby to the Sun comets both in size and in composition; the evolution of dust particles from the distance from the nucleus, the speed of their fragmentation, size and composition are modeled; the contribution of polarized nuclear radiation and molecular emissions to the polarization of dust comets 2P / Encke and C / 2011 was determined for the first time KP36 (Spacewatch). A low value of the polarization maximum for comet C / 2018 V1 (Machholz-Fujikawa-Iwamoto) was detected. The parameters of the phase curve of polarization of ANZ 162082 (1998 HL1), its geometric albedo (0.2 ± 0.07), and diameter (-315 m) were determined.  Product Description popup.authors Ivanova Oleksandra V.
