Source: Space-Track.org CDM Public — refreshed up to every 8h via OrbitSmith triage cron. Events without a reported PC are grouped into NO PC DATA. Empty risk tiers are hidden from the legend. Risk bands (HIGH/MODERATE/LOW/NEGLIGIBLE) are OrbitSmith-defined display groupings and are not official NASA/ESA categories — see About → Data & Methods.
