At a GlanceAI
Introduces “stable chaos”: asteroid orbits can be long-lived yet show chaotic dynamics near mean-motion resonances.
SummaryAI
The paper highlights that chaotic behavior in orbital motion does not necessarily imply rapid instability or ejection, introducing the idea of “stable chaos” in the Solar System. In the context of mean-motion resonances, it emphasizes that resonance-related perturbations can generate chaos while the orbit remains bounded for very long times. This reframes how dynamical maps and resonance diagnostics should be interpreted: chaos indicators alone may overstate true long-term risk. The concept helps explain why some resonant or near-resonant small bodies can persist despite having formally chaotic trajectories.
