YR4 has now been reassigned to Torino Scale Level Zero, the level for 'No Hazard' as additional tracking of its orbital path has reduced its possibility of intersecting the Earth to below the 1-in-1000 threshold.

Even in the increasingly unlikely event of an impact from YR4, Oregon and the Pacific Northwest appear to be safe from impact. Computer models showed areas of South America, Africa and southeast Asia would have the highest risk in the event of an impact, based on what astronomers know about the asteroid’s orbit.
