这一发现源自显示未来数十亿年中行星轨道会如何演变的模拟计算。
The finding comes from simulations to show how orbits of planets might evolve billions of years into the future.
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.
他立即运行中心的轨道预测软件，计算小行星离地最近距离，然后打电话警告切斯利一场即将发生的小行星撞地球。
He ran it through MPC's orbit-projection software, which can tell how close an asteroid will come to Earth, and phoned Chesley to alert him of an impending collision.
下面显示的行星，每个位串行加法器控制，显示的元素，太阳系仪，其中每一个对应计算出地球的轨道。
Below the planetary display, each bit serial adder controls one element of the display, the orrery, each of them corresponding to calculate that planet's orbit.
张钰哲致力于观察和计算小行星和彗星的轨道。
He devoted himself to observing and calculating the orbits of minor planets and comets.
该术语也用于描述观测的某天体(小行星或彗星)的位置与轨道计算值之间的差别。
It is also used for the difference between the observed position of an object (minor planet or comet) and the position calculated from an orbit.
