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.

NASA has revised the chances of asteroid 2024 YR4 hitting Earth on December 22, 2032, reducing it to 0.28%. There are indications it may collide with the Moon instead.

YR4 has a 2% chance of hitting Earth in 2032. Astronomers are tracking it to refine estimates of its size and orbit to see how much of a risk the space rock poses.

A NASA asteroid tracker explains how scientists are calculating the risk to Earth from asteroid 2024 YR4. Archaeologists are piecing together the world’s oldest known rune stone. It could shed light on the origins of early written Germanic languages and who inscribed it.
