How we classify risk
Each object's risk class is computed locally from two NASA NeoWs signals: miss distance (in lunar distances) and estimated diameter. "Potentially hazardous" is NASA's own flag — applied when an object's orbit brings it within 0.05 AU of Earth and it's at least ~140 m across. That flag indicates monitoring interest, not an impact prediction.
Passes at a comfortable distance — routine flyby.
Close-but-comfortable. Interesting enough to highlight.
Inside 10 lunar distances — actively tracked.
Large object passing unusually close — refined each observation.
