But their forecast that it would come within 30,000 kilometers of our planet in 2029 (closer than some geostationary communications satellites, as well as the Moon) is more likely to please astronomers than international security experts. Some unknown comet or other space object could fly near enough to the asteroid in the next few decades to change its predicted path, perhaps in a way that redirected it toward Earth.
但据他们预测，阿波菲斯将于 2029 年迫近到距地球 3 万公里以内（比一些地球通讯卫星乃至月亮距离地球更近），天文学家可能会为此感到兴奋，而国际安全专家却忧心 忡忡 。在未来几十年内，某些未知的 彗 星或其他天体接近这颗小行星，改变其运行轨道，使它对准地球撞过来，这种可能性并非没有。
