摘要
近地小行星与地球碰撞虽然罕见但可能会造成灾难性后果。近年来,各国加强了对近地小行星的监控、跟踪力度,并且实施了几次卓有成效的探测任务,如何防御近地小行星威胁的研究越来越多。总结了目前近地小行星的主要观测监视设施和现状,讨论了国际上对小行星威胁的评估情况,分析和评估了目前提出的防御手段的研究现状及其可行性。
Terrestrial impact by a near-Earth asteroid or comet occurs rare but may result in potentially catastrophic hazard.The researches on how to defense threat of near-Earth asteroids attract more and more attention. The paper summarizes the current situation of survey and detection of near-Earth asteroids and the major survey telescopes. And it also discusses the current state of assessing the potential impact risk and sequence in the recent researches. Finally, several proposed approaches that could prevent or mitigate the effects of potential impacting of near-Earth asteroids are analyzed and evaluated.
