Definition

The process by which a third body enters the gravitational sphere of influence of a primary and becomes gravitationally bound. In the restricted three-body problem this can be achieved through potential barrier penetration.

Application Value

In orbit design and optimization, this concept is used to analyze spacecraft motion characteristics in the cislunar multi-body gravitational field, providing a theoretical basis for low-energy transfer trajectory design.
