Size comparison
(2026 HF2) is about 116% of School bus.
Hypothetical impact energy
Would cause significant local destruction. Comparable to a large nuclear weapon.
What this means
This object passed within lunar distance — closer than the Moon's average orbit (0.3 LD). Its combination of size and miss distance puts it on the active monitoring list, but no impact trajectory is 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.
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.
