Gravitational Potential

Author: Tianjiang Shuo Website: https://cislunarspace.cn

Definition

The potential energy per unit mass at a point in a celestial body's gravitational field, inversely proportional to the distance from the gravitational center.

Application Value

This concept plays a key role in trajectory transfer design, helping evaluate transfer costs and flight time to provide quantitative basis for mission trade studies. Combined with global search algorithms, multiple solution families and Pareto frontiers can be identified to guide orbital design decisions.
