The last decade has become a significant time for robotic exploration bodies of the solar system. Among such research programmes was The Dawn Mission to asteroid Vesta and dwarf planet Ceres, whose results allow us to carry out a detailed analysis of asteroid (4) Vesta surface properties by using methods that were developed and effectively used in the analysis of the Moon data.

Since NASA is planning Lucy Mission to Trojan asteroids, comparative ground and space photometry are very important for calibrating further ground-based photometric observations. The asteroid Trojan Hektor (624) was observed at the Lisnyky astronomical station (MPC 585). For observations we used the 0.7 m (f/4) reflector AZT-8 with FLI PL4710 CCD camera and filter R of Johnson – Cousins...
Using the software Astrometrica and Maxlm DL5 to the observed data for two distant comets C / 2014 B1 (Schwartz) and C / 2012 K6 (McNaught) obtained on the 2nd telescope at Terskol, their values of apparent magnitude were obtained. Using the value of the visible stellar magnitude, the absolute stellar magnitude, dust productivity in the form of the parameter Afρ were calculated, and the...
In this work, the results and analysis of my observations of the Perseid meteor shower at the maximum of its activity on 12-13 August in 2017 - 2020 are presented. They were the one-sided visual observations, that were carried out in Kyiv by the astronomical group of gymnasium № 59. Observations and processing of data observations were carried out using the methodology of the International...

Active asteroids are relatively new objects to study in the Solar system; they have asteroid-like orbits but exhibit comet-like activity. The study of active asteroids allows one to cross the traditionally drawn lines...
Based on observations of the comet C/2020 F3 (NEOWISE) from July 23 to August 11, 2020, the dust tail of the comet was studied at the Gissar Astronomical Observatory of the Institute of Astrophysics of the NAST. The cometocentric coordinates of the comet's tail were determined by Moiseev's method and the effective acceleration of dust particles of the comet's tail was calculated. The results...
The report considers the analysis of the correlation coefficient of photometric parameters of selected short-period Jupiter family comets on the Wolf number and the area of sunspots. It is shown that the correlation coefficient of photometric parameters of some comets is not very strongly related to the activity of the Sun.
