Compare against
Hypothetical impact energy
0.0 MtTNT equivalent
Would likely explode in the atmosphere as a fireball (airburst). Minor ground damage possible.
Hiroshima equivalents
1
Estimated mass
749,204 kg
Diameter used
8 m
Impact velocity
13.9 km/s
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 54 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.
