2022年小行星撞地球？NASA密切观察中

The impact would be more than 15 times larger than the atomic bomb dropped on Hiroshima in 1945, which liberated energy equivalent to approximately 15 kilotons of TNT.

这颗小行星如果撞击地球，带来的影响将是1945年投放在广岛的原子弹的15倍以上，广岛原子弹释放出的能量相当于约1.5万吨TNT炸药。

Scientists have said that if JF1 were to hit a populated area, it would wipe out an entire city instantly, potentially causing millions of deaths.

科学家们曾表示，如果JF1撞到人口稠密的地区，将立即摧毁整个城市，有可能造成数百万人死亡。

But they warn that even if it were to splash down in the remotest part of the Pacific Ocean it would still cause devastating tsunamis and a “nuclear winter” that could severely impact life on Earth.

但他们警告说，即使它坠落在太平洋最偏远的地方，也会引发毁灭性的海啸和“核冬天”，可能对地球上的生命造成严重影响。

As a result, the asteroid has been flagged for close attention by their near-Earth monitoring system, Sentry.

因此，这颗小行星被美国国家航空航天局的近地监测系统“哨兵”标记为密切关注。

NASA said: “Sentry is a highly automated collision monitoring system that continually scans the most current asteroid catalogue for possibilities of future impact with Earth over the next 100 years.”
