摘要

在2022年，RAS的主（普尔科沃）天文台的望远镜获得了一颗潜在危险的小行星（138971）2001 CB21在接近地球时的天体测量和光度系列观测。根据获得的数据和MPC网站的数据，改进了小行星的轨道，研究了与地球和金星相遇的情况，并评估了非引力效应对其运动的影响。基于对该小行星的光度观测，构建了光曲线，确定了其轴向自转周期R = 3.305±0.002 h。

Astrometric and Photometric Studies of a Potentially Hazardous Asteroid (138971) 2001 CB21

In 2022, the telescope of the Main (Pulkovo) Astronomical Observatory of RAS obtained astrometric and photometric series of observations of a potentially dangerous asteroid (138971) 2001 CB21 during its approach to Earth. Based on the data obtained and data from the MPC website, the asteroid’s orbit was improved and the circumstances of the encounters were investigated with the Earth and Venus and an assessment was made of the influence of nongravitational effects on its motion. Based on photometric observations of the asteroid, a light curve was constructed and its axial rotation period was confirmed: R = 3.305 ± 0.002 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.
