Size comparison
(2007 UW1) is about 124% of Football pitch.
Hypothetical impact energy
Would cause significant local destruction. Comparable to a large nuclear weapon.
What this means
This object passed at 33 LD — safely distant and of interest mainly to orbital surveys. No impact trajectory has been detected. At an estimated diameter of up to 171 m, it's large enough to warrant continued orbital refinement each time it's observed.

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.
