At more than 360 meters in diameter, the asteroid, Apophis, is a dozen times larger than the Tunguska space object (presumably a meteorite or comet) that devastated a large part of eastern Siberia a century ago. As far as can be determined, that object detonated on June 30, 1908, with the power of a nuclear weapon, felling 80 million trees over a 2,000-square-kilometer area.
这颗小行星名叫“阿波菲斯”（ Apophis ），直径 360 米，比一世纪前导致西伯利亚“通古斯大爆炸”的天体（可能是一颗陨石或 彗 星）大 12 倍。据推测，该天体于 1908 年 6 月 30 日发生爆炸，能量相当于核弹，冲击波推到了方圆 2000 公里内的 8 千万棵树木。
