Hypothetical impact energy

0.2 MtTNT equivalent

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

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.

Time until closest approach

0d01h52m06s

(2025 UM7) will pass 60.5 LD from Earth on Wed, Apr 29 · 00:00 UTC

What this means

This object will pass at 61 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.
