Hypothetical impact energy

1.0 MtTNT equivalent

Would cause significant local destruction. Comparable to a large nuclear weapon.

Estimated mass
54.3M kg
Diameter used
34 m
Impact velocity
12.5 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 170 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.
