The dynamics of the Earth-Moon system is quite different from the Sun-Earth system especially after a long duration for the gravitational attraction of the Sun.

由于在地-月系统中太阳的引力不可忽略，特别是在长时间作用以后，其动力学行为与摄动力较小的日-地系统有明显的不同。

Our planet Earth, together with other planets, revolve around our Sun in what is called our Solar system.

我们的行星地球，连同其他行星，围绕我们的太阳旋转，这就是我们的太阳系。

Initial measurements were made in March, but now the binary system has moved almost directly behind the sun from our perspective on Earth, making the pair currently invisible to telescopes.

今年三月份的时候科学家们就进行了初步的测量。但是现在，以我们在地球上的视角来观察，这对双星系统已经移动到了太阳的正后方，这就导致当前无法使用望远镜来观察这对双星。

And not just man. The whole Earth was made from dust particles in orbit around the primitive sun, as were all the other solid objects in the solar system.

而且不仅仅人是尘土造的，包括地球在内的、整个太阳系的固体物质都是由环绕早期太阳的尘埃造的。
