ATLAS is intended to spot mid-sized city killers like 2012 DA14.

Astronomers reckon the risk from these is at least as great as that from the biggest onesbecause there are many more of them.
天文学家估测这类小行星的威胁绝不在那些更大的小行星的威胁之下,因为数量实在太多。
Exactly how many more, though, is hard to say because, being small, they are hard to see.
不过至于准确数量却很难说,因为他们实在太小难以被发现。
ATLAS should be able to spot a rock on a collision course a few days before it hits, givingtime to organize a hasty evacuation.
