Lunar Gravity Field

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

The gravitational field generated by the Moon, which deviates from a simple central field due to non-uniform internal mass distribution. Described through spherical harmonic expansions, with higher-degree coefficients capturing finer spatial details. Near low lunar orbits, high-degree gravity terms significantly affect orbital evolution.

Application Value

This concept has practical applications in cislunar space science and engineering. Related research supports the planning, implementation, and operations of cislunar missions, forming an integral part of the knowledge system in this field.
