Size comparison
(2022 UU8) is roughly the length of School bus.
Hypothetical impact energy
Would likely explode in the atmosphere as a fireball (airburst). Minor ground damage possible.
What this means
This object passed just beyond lunar distance (8.7 LD) — close enough to be tracked, but well outside any hazardous range. 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.
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.
