Description: 潮汐力拉伸天体，使其形状变长。例如，月球将地球表面的海水拉伸成两个凸起，这就导致了地球上的潮汐。

任何两个大质量天体都会对彼此施加潮汐力。质量越大的天体产生的潮汐力越大，而距离越近，潮汐力也越强。这些潮汐力可能强到足以将其中一个天体撕成碎片。

对于特定质量和大小的天体（例如小行星或卫星）来说，当它靠近另一个大质量天体时，在一定的距离范围内，它会被另一个天体的潮汐力撕成碎片。这个距离被称为 "洛希极限"。

洛希极限的一个常见例子是围绕巨行星运行的岩石和冰质卫星。如果卫星与巨行星的距离小于洛希极限，它就会解体，在巨行星周围形成一个物质环。

在月球和太阳系其他岩石天体上可以看到一连串被称为 "链坑 "的陨石坑，证明了经过的小行星在到达洛希极限时解体，导致它们以一串较小的天体的形式撞击，而不是一个大天体。
