Most NASA/JPL missions were dedicated to tracking the Anomaly which proved difficult due to its erratic velocity and orbital dynamics.

大多数 NASA/JPL 的任务是致力于追踪 Anomaly 的行踪，但事实证明， Anomaly 的速度不稳定无规律，其运行轨道也处于动态状况，因而难以追踪。

The combinations, and movements, of these masses with gravitational, centrifugal and orbital velocity vector forces, create what we call the equatorial bulge, and thus, the axis of figure.
