Resonances, N-Body Dynamics & Gravity Assists: Observation, Measurement & Evidence

Real planetary systems contain many mutually gravitating bodies, so their motions depart from ideal two-body ellipses. N-body dynamics predicts long-term planetary stability, resonant migration, asteroid hazards, spacecraft trajectories, and the evolution of exoplanet systems.
