Abstract The study of near-Earth space includes the detection and investigation of an increasing number of space debris objects by ground-based optical telescopes. There is no natural cleansing of space in the geostationary region. The telescope Zeiss-2000 with a two-meter aperture of the Terskol observatory is the largest optical instrument regularly used for space debris investigations. One of the main purposes in «Astronomy in the Elbrus region» international program’s boundaries is the detection and characterization of small fragments of debris,which are invisible for smaller telescopes. During observations on photometric nights we usually detect 4-5 unknown fragments of 17-21st star magnitude. In this article, we present orbital parameters and physical characteristics of several small-sized fragments of the space debris detected at the Terskol observatory in 2016-2017.

2016-2017年Terskol天文台探测到的小型空间碎片物体特征

摘要 近地空间研究包括通过地基光学望远镜探测和调查越来越多的空间碎片物体。地球静止区域没有自然的空间净化。Terskol 天文台孔径为 2 米的 Zeiss-2000 望远镜是经常用于空间碎片调查的最大光学仪器。《厄尔布鲁士地区的天文学》国际计划的主要目的之一是探测和表征小碎片碎片，这些碎片对于较小的望远镜是不可见的。在光度夜观测期间，我们通常会检测到 4-5 个 17-21 星等的未知碎片。在本文中，
