洛希极限

But how can the differentiated satellite be brought so close to the planet, within the Roche limit?

但这些已分化的卫星是怎么进入土星洛希极限内的？

Yet Saturn´s rapid rotation meant it could hold a satellite within its Roche limit until the bombardment.

然而，土星的高速自转意味着它能够在洛希极限中保持着一个卫星直到“猛烈轰击”。

Triton will one day enter within Neptune´s Roche limit and become totally obliterated.

崔顿将缓慢地经螺旋轨道接近海王星，而当它到达洛希极限时最终将被海王星的引力撕成碎片。

Similarly, if a pre-existing icy body were to be placed within Saturn´s Roche limit, it would be destroyed by the planet´s tides.

同样的，如果在土星洛希极限内存在一个冰质天体，它必然的会被潮汐力摧毁。

The Roche limit for the earth is a small fraction of the radius of the moon´ s orbit.

地球的洛希极限相当于月球轨道半径的一小部分。
