Size comparison
(2013 JL22) is about 76% of Eiffel Tower.
Hypothetical impact energy
Would devastate a large metropolitan area. Regional effects including earthquakes and firestorms.
What this means
This object passed at 129 LD — safely distant and of interest mainly to orbital surveys. NASA classifies it as "potentially hazardous" because it meets both the size (~140 m+) and proximity (within 0.05 AU) criteria, not because an impact trajectory has been detected. At an estimated diameter of up to 348 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.
