   Resonance and Stability
   Many multi-planet systems exhibit orbital resonance, where the orbital periods of planets are related by small integer ratios (e.g., 2:1, 3:2). While some resonant chains indicate a stable, long-term configuration (e.g., the TRAPPIST-1 system), others suggest recent, violent dynamical restructuring events. The long-term stability of a planetary system is mathematically modeled using the [restricted thre…
