2013年2月15日，俄罗斯车里雅宾斯克市附近的小行星撞击是自1908年通古斯事件以来地球上最大的一次空中爆炸，在一个人口超过100万的地区造成了自然灾害。由于它发生在一个拥有现代消费电子产品、现场传感器和实验室技术的时代，对撞击事件和造成它的流星体进行了前所未有的测量。在这里，我们使用从天文学、行星科学、地球物理学、气象学、陨石学和宇宙化学以及社会科学调查中获得的综合数据，记录了所发生的事情。对车里雅宾斯克事件的充分了解为校准该事件提供了机会，对近地物体的研究和制定行星保护减灾战略都有影响。
The asteroid impact near the Russian city of Chelyabinsk on 15 February 2013 was the largest airburst on Earth since the 1908 Tunguska event, causing a natural disaster in an area with a population exceeding one million. Because it occurred in an era with modern consumer electronics, field sensors, and laboratory techniques, unprecedented measurements were made of the impact event and the meteoroid that caused it. Here, we document the account of what happened, as understood now, using comprehensive data obtained from astronomy, planetary science, geophysics, meteorology, meteoritics, and cosmochemistry and from social science surveys. A good understanding of the Chelyabinsk incident provides an opportunity to calibrate the event, with implications for the study of near-Earth objects and developing hazard mitigation strategies for planetary protection.
