如果您有最后的愿望，现在是时候使用它们的时候，因为小行星2016 AJ193即将在本周末对地球进行“亲密”访问。
Asteroid 2016 AJ193, which was first spotted by Haleakala Observatory’s Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) facility in 2016 (hence the name), is reported to fly by our planet this Saturday at a distance of 2.1 million miles which is approximately 8.9 times the distance between Earth and the Moon. While that doesn’t really seem like too close of an encounter, it has officially been classified as “potentially hazardous” since it’s one of the closest approaches for several decades. *轻笑*我们处于危险之中（不是真的……对吗？）
在谈论小行星的大小时，据信它的宽度约为4800英尺，已与三个帝国州立建筑或四个埃菲尔塔的长度进行了比较！关键是，它的尺寸非常出色！不仅大小，而且小行星在太空中飞行的速度也令人印象深刻，速度为58,000 mph或每秒16英里！当然，当我们的星球从这个幅度和速度的外太空中一个天文机构时，研究人员将进行实地考察。通过使用雷达技术，能量脉冲将被爱游戏ayx体育发送到外太空中，该空间将用于计算小行星最接近地球时的形状和旋转。
但是，出现的另一个问题是，如果空间中的小行星或其他物体决定朝我们的星球走去，我们是否能够使用太空飞船来偏转其路线，或者我们会完全被拧紧吗？To answer that question, it seems like NASA is working on a project called DART : Double Asteroid Redirection Test whose goal is to see if kinetic impactor technology would work in that scenario since asteroid detection and deflection is a crucial task and we wouldn’t want to be caught off-guard if an asteroid decides to pay us a visit.
