比方说，如果不同望远镜上的时钟走得不一致，那么某一确切时刻小行星坐标的测量将互相冲突，导致轨道推测计算错误。
If the clocks on the different telescopes didn't agree precisely, for example, then their calculations of the asteroid's location at a given moment would conflict, distorting his trajectory.
这个新模型追踪了海王星轨道外数无数个微小物体的运行轨迹，它可以帮助天文学家计算出其他星系尘埃盘中行星的特性。
The new model, which tracks thousands of tiny particles beyond the orbit of Neptune, could help astronomers work out the properties of planets in other stars' dust disks.
