小行星撞地球或使人类变成"吸血鬼"

　　Asteroid hunters have found about 903 of an estimated 1,050 near-Earth objects (NEOs) with diameters of 1 kilometer or greater as of October 1. That still leaves well over 100 objects in the 1-2 kilometer size undiscovered.

　　据估计，截至10月初，直径大于等于1000米的近地小行星约有1050个，行星探测器已发现903个，而还有100多个直径为1000到2000米的小行星尚待发掘。
