英文摘要 | Near-Earth Asteroids (NEAs), as accessible targets can be used to study the origin and the evolution of asteroids of the solar system, and taken as the sources of energy for the deep space exploration in the future. Another important thing is that the NEAs have some probability to hit the earth. In order to estimate accurately the probability of hazard, it is important to obtain as many as possible new observations of NEAs. At present, kinds of ground- and space-based sky survey projects around the world are running or in prepared, in which more or less asteroids are included in the survey observations. The brightness and astrometry position of involved asteroids can make significant contribution to the phyiscal study of asteroid and orbit improvement. He, we present measurement result of astrometry position of Apophis which are observed by an exoplanets survey. To extract the brightness and astrometry data of asteroids, we develop a special pipeline to identify asteroids firstly in the field of view in a single night, and then to derive the astrometry position for those identified asteroids. Here, we’d like to present the 6 nights astrometric measurement results of Apophis (99942) extracted from the Yunnan-HK exoplanet survey. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. |
