3D Orbital path
Size comparison
(2011 BG24) is about 160% of School bus.
Hypothetical impact energy
Would likely explode in the atmosphere as a fireball (airburst). Minor ground damage possible.
Time until closest approach
(2011 BG24) will pass 184.4 LD from Earth on Wed, Jun 17 · 00:00 UTC
What this means
This object will pass at 184 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.
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.
