Abstract
In 2023–2024, astrometric and photometric observations of the potentially hazardous asteroid 139622 (2001 QQ142) were carried out using telescopes of the Main Astronomical Observatory of the Russian Academy of Sciences. A series of astrometric observations of the asteroid positions have been obtained, which have a root-mean-square accuracy of one observation for ZA-320M σ = ±0″.21 and for MTM-500M σ = ±0″.07. The evolution of its orbit and the circumstances of its close approaches to Earth were studied, and the influence of nongravitational effects on its motion was estimated. Based on photometric observations of the asteroid in the integral bands of the telescopes, a light curve was constructed, and its axial rotation period was refined: P = 17.0232 ± 0.0040 h.
期刊介绍：
Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
