IAWN Issues 19% Asteroid Impact Alert for 2038 Ahead of 2027 Defense Conference

Summary
A hypothetical asteroid in a Planetary Defense Conference 2027 exercise carries a 19% chance of hitting Earth on July 10, 2038, prompting IAWN to issue a formal notification.
NASA JPL, ESA and Italy's NEODyS calculated the risk after Vera C. Rubin Observatory detections and archival data sharpened the object's orbit, first lifting the impact probability to 16% and later higher.
The scenario puts an 80-85 meter asteroid on a risk corridor spanning the Pacific, the U.S., Canada, the Atlantic and parts of southern Europe and Turkey, with expected local-to-regional airburst damage.
IAWN's alert was triggered after the probability crossed its 1% threshold; a second notice in the exercise updates the object's physical properties and warns new observations could either raise the odds or cut them to zero.
IAA is using the scenario to steer research abstracts for its 2027 conference, where planetary defense specialists will test response planning against a plausible impact case.
If a hidden asteroid had a 19 percent chance of striking Earth in 2038, could our current technology actually prevent a regional catastrophe?
How would global populations react to a twelve-year warning of a potentially devastating asteroid strike across North America and Europe?
What happens when hidden cometary outgassing alters an incoming asteroid's path, rendering our most advanced planetary defense predictions completely useless?
