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

1 articles · Updated · leonarddavid.com · Aug 13

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.
