Apophis-的意思|示意

"You have to be careful about moving asteroids around in space," he adds, lest a deflection inadvertently steer Apophis toward Earth.

“对于在太空中移动小行星，你必须万分小心，”他补充说，否则一偏转却可能无意中使阿波菲斯朝向地球。

There is, according to the latest calculations, no danger from Apophis either.

根据最新的计算，阿波菲斯还没给我们带来什么危险。

The schoolboy took into consideration the risk of Apophis running into one or more of the 40, 000 satellites orbiting Earth during its path close to the planet on April 13 2029.

马夸特考虑到了阿波菲斯行星在2029年4月13日靠近地球时与一颗或多颗围绕地球运转的卫星相撞的可能性。目前地球周围的卫星达四万颗。

The Russian scientists are also hedging their bets. Professor Leonid Sokolov of St. Petersburg State University remarked that 99942 Apophis would most likely disintegrate before hitting Earth.

俄国科学家也在做以备万一的计划。圣彼得堡国家大学的李尔尼德·索科尔夫教授说，阿波菲斯99942更有可能在撞上地球之前就已经被击碎。

Those satellites travel at 3.07 kilometres a second (1.9 miles), at up to 35,880 kilometres above earth -- and the Apophis asteroid will pass by earth at a distance of 32,500 kilometres.

这些卫星位于地球上方3.588万公里，运行速度为每秒3.07公里，而阿波菲斯行星则预计将在距离地球3.25万公里的地方经过。

In 2004, NASA scientists announced that there was a chance that Apophis, an asteroid larger than two football fields, could smash into Earth in 2029.

在2004年的时候，美国航空航天局的科学家们宣布阿波菲斯这个比两个足球场还大的小行星，可能会在2029年撞击地球。
