Object of study. The Small Bodies of the Solar System (MTCS) are comets, asteroids, Centaurs, meteoroids, and potentially dangerous Earth objects.
The goal of the work. MTSS observations, analysis of results and on their basis research of physical state and chemical composition of bodies of different dynamic classes; identifying dynamic relationships between different MTSC populations by investigating 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. During the implementation phase of the 1st stage of the GDR (2019), a large array of photometric, polarimetric, spectral and astrometric data was obtained for 47 comets, 34 asteroids, 9 planets and 2 centaurs on different telescopes of the world and AO KNU. A large number of meteor images and spectra were obtained during basic Perseid meteor shower observations in August 2019.
Short- and long-period comets have been found to have typical polarization phase dependencies, although they have different origin and evolution; first obtained the physical characteristics and chemical composition of the interstellar comet 2I / Borisov; rapid color changes were explained and it was concluded that color could not be a constant feature of comets; found that dust in distant comets differs from dust in comets close to the sun in both size and composition; the evolution of dust particles with distance from the nucleus, their fragmentation rate, size and composition were modeled; for the first time, the polarization of the ANS 162082 (1998 HL1), its geometric albedo, and diameter were measured; the phase polarization curve of Europe and its parameters are determined with high accuracy; for the first time kinematic and photometric parameters of meteors from the Leonid flow, which have a diffuse structure at altitudes of 118–125 km, were determined, and
