Assumes stony composition (2,600 kg/m³). Actual energy depends on composition, angle, and atmospheric interaction. This is NOT a prediction — this asteroid is not on a collision course.

What this means

This object passed at 176 LD — safely distant and of interest mainly to orbital surveys. No impact trajectory has been detected.

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.

No risk

Passes at a comfortable distance — routine flyby.

Watch

Close-but-comfortable. Interesting enough to highlight.

Notable

Inside 10 lunar distances — actively tracked.

Significant

Large object passing unusually close — refined each observation.
