原文：

An object as small as 1 millimeter can wreak havoc in space because it will have a similar impact as a bowling ball barreling down at 100 kilometers per hour on earth. Some estimates say that there are about 130 million such objects orbiting the earth.

译文：

一颗直径仅1毫米的物体在太空中也能造成严重破坏，其撞击力相当于地球上时速100公里飞驰的保龄球。据估计，地球轨道上约有1.3亿个此类微小物体。
