Spatial Bi-Circular Model, SBCM

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

An analytical four-body model including gravitational forces from the Sun, Earth and Moon, assuming the Earth-Moon barycenter moves in Keplerian circular motion around the Sun, and the lunar orbital plane has an inclination of 5°9′ relative to the ecliptic plane, used for studying low-energy Earth-Moon transfer trajectories.

Application Value

This concept has application value in cislunar space research and engineering practice, helping to understand core principles of the field.
