摘要

摘要在本文中，我们考虑的是一个刚体的吸引场接近于一个动态对称的刚体。本文研究的问题是如何用三个同质球的吸引力场来近似这个吸引力场，从而使这些场的引力势能的序列展开到五阶小次项时重合。以小行星 (433) 爱神号为例，研究了三球近似法。

Approximation of the Attractive Field of a Body Close to Dynamically Symmetrical Using the Attractive Field of Three Balls

In this paper, we consider the attraction field of a rigid body close to a dynamically symmetric one. The question of how to approximate this attractive field by the attractive field of three homogeneous balls so that the series expansion of the gravitational potential for these fields coincides up to terms of the fifth order of smallness is studied. As an example, the three-ball approximation as applied to asteroid (433) Eros is considered.
