What mechanism involving Neptune creates safe, long-lived paths for smaller, icy bodies beyond it?
Answer
Orbital resonances, locking objects in specific orbital ratios
Neptune influences distant icy bodies by carving out stable orbital resonances, locking them into specific orbital ratios that help maintain safe, long-lived paths.
