At a GlanceAI
Updated dynamical classification of 3357 multi-opposition TNOs/Centaurs using 10 Myr integrations, mapping resonance and scattering populations.
SummaryAI
The authors provide a current dynamical census of 3357 multi-opposition outer solar system objects, assigning each to Jupiter-coupled, Centaur, scattering, detached, classical, or resonant categories using the Gladman et al. scheme. By reporting secure vs insecure classifications, the work highlights where present-day orbit uncertainties still limit confident long-term dynamical labeling. It also quantifies which mean-motion resonances are most populated observationally, with the 3:2 leading by a large margin, providing an up-to-date reference set for studies of trans-Neptunian dynamical structure and transport pathways.
