Multi-Body Dynamical Environment

Author: Tianjiang Shuo

Definition

The spacecraft operating space where gravitational fields of multiple celestial bodies significantly affect motion, distinct from two-body and restricted three-body problems. In cislunar space, the combined gravitational influence of Earth, Moon, and Sun governs orbital evolution. Near libration points and Sun-Earth weak stability boundaries, multi-body coupling produces far more complex orbital structures than two-body dynamics, yet simultaneously provides pathways for low-energy transfers.

Application Value

In cislunar space, the combined gravitational influence of Earth, Moon, and Sun governs orbital evolution. Multi-body coupling produces orbital structures far more complex than two-body dynamics, but also provides pathways for low-energy transfers. Orbit designers must fully consider the multi-body dynamical environment.
