Moonstruck
沉迷于幻想
The most widely accepted theory of how the moon formed suggests it is the result of a cosmicsmash-up between Earth and an object roughly the size of Mars that happened about 4.5 billionyears ago during the solar systems turbulent youth. This impact would have sprayed hugequantities of material into space, forming a ring around Earth similar to, but much thicker than,those that now adorn Saturn.
月球如何形成的最广泛接受的理论表明,大约发生在45亿年前的年轻的太阳系动荡期间,地球和一个大约火星大小的物体间的宇宙大碰撞的结果而产生了月球。这次碰撞已将大量的物质散发到了太空,从而形成了环绕地球的光环,类似于那些现在装饰土星的光环,但是要厚得多。
The moon is thought to have condensed rapidly from this ring. Computer simulation of theprocess suggests, however, that several smaller moons may have formed at the same time.Some would then have collided with Earth or the moon, while others would have been ejectedfrom the system altogether. But one or more of them often end up, according to thesimulations, in what are known as Trojan orbits, where they followed the proto-moon endlesslyaround Earth.
月球被认为是从这个光环的气体凝聚而成。然而,计算机模拟的过程表明,这次大碰撞可能在同一时间形成了几个更小的卫星。然后,有些卫星就与地球或月球相撞,而其它卫星则完全被太阳系喷射出来。但,根据计算机多次模拟,其中的一个或多个卫星往往停留在被称为特洛伊星座的轨道上而终结。这些卫星在那儿伴随着永无休止地围绕地球的原月。
