据天文学家估计,J1407b的轨道周期大约在10年左右。
Astronomers estimate that the ringed companion J1407b has an orbital period roughly a decade in length.
因此,典型恒星的轨道周期仅与行进路径的长度成正比。
Hence the orbital period of the typical star is directly proportional only to the length of the path traveled.
莫尔纳最初对2022年双星合并的预测是基于KIC9832227的轨道周期的指数明显衰减而得出的。
Molnar's original prediction of a 2022 merger was based off theapparent exponential decay of KIC 9832227's orbital period.
但Barnes博士表示,地球自转慢慢减速,直到它与月球的轨道周期相同。
However, Barnes says eventually the Earth's rotation willkeep slowing until it's the same as the Moon's orbital period.
作为一个联星系统,估计他们会有至少19,500年的轨道周期和2,000天文单位的距离。
As a binary star system,they would have an estimated orbital period of at least 19,500 years and a present-day separation of around 2,000 Astronomical Units.
在L1点,物体的轨道周期恰好等于地球的轨道周期。
At the L1 point, the orbital period of the object becomes equal to Earth's orbital period.
但Barnes博士表示,地球自转慢慢减速,直到它与月球的轨道周期相同。
