![]() The actual excursion is slightly less than the maximum shown, due to the orbit being elliptical. Tiny crescents depict quasi-stable points utilized for satellites ( b) Quadrant of the lunar orbit showing a to scale comparison of the nearly circular barycenter orbit (solid line) to the Moon’s sinuous orbit (pink dots), which reaches a maximum of ~405,000 km from Earth (e.g., ). Large crescents depict stable orbital positions at the 60° and antipodal Lagrangian points. Key features of the 3-body Earth-Moon-Sun system: ( a) Schematic of stable 3-body orbits around the stationary Sun in a plane fixed in space.
