Assessment of Close Approaching Between ASO-S Satellite and Other Objects in Space

Advanced space-based solar observatory,short for ASO-S, has been in orbit for more than a half year. Most of the performance of ASO-S are demonstrated to be wholesome. Some achievements were reported in some academic journal or public media. In this paper, the space safety of ASO-S will be focused on. Based on cyber-accessible data set.the objects' orbits are simulated, further, the approaching events between ASO-S and other neighboring flying objects have been presented. The approaching objects are briefly introduced and discussed. Faced up with such a busy space traffic, emergency measures are proposed to prevent the ASO-S satellite from colliding with other neighboring flying objects in space.
