由于地球和木星的公转轨道是椭圆的，同时地球的轨道周期快于木星，从我们的角度观察，就像“追上”了这颗巨型气态行星。
Due to the near-circular orbits of Earth and Jupiter, as Earth has a faster orbital period than Jupiter, from our point of view we will appear to "overtake" the gas giant.
有着一个少于200年的轨道周期的彗星被称作“周期彗星”，其中最著名的可能要数哈雷彗星，它每76年围绕太阳运转一圈。
A comet with an orbital period of less than 200 years is called a "periodic comet", of which the best known is probably Halley's comet, which orbits the Sun every 76 years.

Changes in the eccentricity of Earth's orbit occur in a cycle of about 96,000 years.
这些数据已经建立了地球轨道变化和冰期周期之间的强有力的联系。
These data have established a strong connection between variations in the Earth's orbit and the periodicity of the ice ages.
人们早就知道，地球围绕太阳的轨道会周期性地变化，周期性地影响太阳辐射照射地球的方式。
It is long known that Earth's orbit around the Sun changes periodically, cyclically affecting the way solar radiation strikes the Earth.
除了这个，还能得到半径的大小，速度以及周期，假设你在地球上，和这些恒星环绕的，轨道同处一个平面。
And out of this information you get the radius, the velocity and the period, assuming that you are on Earth in the plane of the orbit of the stars.
