摘要
小行星环境特性不仅是小行星科学研究的基础,也是在设计小行星工程任务时所要综合考虑的关键因素。文章通过对现有的研究资料进行总结,从空间环境、表面环境和内部环境3个方面阐述了小行星的环境特性;最后,对中国国家航天局公布的我国首次小行星探测任务的探测目标——近地小行星(469219)2016HO3和主带彗星133P/Elst-Pizarro的特点进行了简要介绍。
The environmental characteristics of asteroids not only are fundamental issues in related scientific researches,but also constitute a principal factor that needs to be comprehensively considered in designing the corresponding exploration missions.This paper reviews the studies of the environmental characteristics of a couple of accessible asteroids in three aspects:the peripheral space environment,the surficial environment,and the internal environment.This paper also discusses the characteristics of two target objects of China’s first asteroid exploration mission announced by China National Space Administration,namely,the near-Earth asteroid(469219)2016HO3 and the main-belt comet 133P/Elst-Pizarro,focusing on their physical and environmental features.
