Lunar Non-Spherical Gravity Perturbation

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

Additional gravitational acceleration due to the Moon's non-uniform mass distribution, including mascons and other anomalous regions. The lunar gravity field is more irregular than Earth's and cannot be neglected in high-precision trajectory modeling when the spacecraft approaches the Moon, requiring accurate lunar gravity field models.
