唯一的另一个已知的以如此奇怪的角度运行的例子是冥王星，直到它降级为矮行星。
The only other known example of such an oddly angled orbit was Pluto, until its demotion to dwarf planet status.
他们提到的引力关键点是天文上的一个精确地带，仅仅微大于小行星本身，在那个点上地球引力的影响可以改变小行星运行的轨迹。
The gravitational keyhole they mention is a precise region in space, only slightly larger than the asteroid itself, in which the effect of Earth's gravity is such that it could tweak Apophis' path.
土星进入天秤座。另一个生时矫正的好建议就是去学习下最近外带行星通过宫位的运行轨迹，尤其是土星和木星。
Saturn ingress into LibraAnother good piece of advice for rectifying a chart is to study recent outer planet transits through the houses, particularly those of Saturn and Jupiter.
另外一个粗略构想是“爆炸偏移”，也就是通过导弹爆炸偏移小行星的运行方向。哈里斯说，这将会是“铤而走险的最后一招”。
One other, coarser idea would be 'blast deflection ' which would involve deterring the asteroid with directed explosive charges. Harris says this would be the 'final, desperate approach. '
第一个被发现的超级地球是围绕PSRB1257+12 运行的两颗行星。
The first super-Earths ever found were two of the planets around PSR B1257+12.
凌日是指行星(本次是金星)运行至太阳和地球之间，因此可以观测到太阳圆盘上有一个小黑点。
A transit occurs when a planet passes directly between the sun and the Earth; therefore the planet, in this case Venus, becomes visible and hence obscures a small portion of the solar disk.
