An asteroid measuring roughly one metre in diameter impacted Earth’s environment on October 22, 2024, solely hours after its preliminary detection. Found by the Asteroid Terrestrial-impact Final Alert System (ATLAS) in Hawaii, the article — named 2024 UQ — approached the planet undetected by international affect monitoring programs earlier than disintegrating over the Pacific Ocean off California’s coast. The European Area Company’s (ESA) Close to-Earth Object Coordination Centre later confirmed the occasion in its November e-newsletter, reporting that monitoring information for the asteroid didn’t attain monitoring programs till after the affect had already taken place.
Restricted Monitoring Knowledge As a result of Detection Timing
In accordance to ESA’s November e-newsletter, 2024 UQ had been picked up by ATLAS’ sky-monitoring telescopes. Nonetheless, the asteroid was solely recognized as a transferring object minutes earlier than it entered Earth’s environment resulting from its location between two adjoining sky fields within the survey system. This detection delay meant that important monitoring information was delayed and unavailable for affect monitoring centres, which monitor potential near-Earth object (NEO) threats. Affirmation of the asteroid’s affect was made potential by information from the Nationwide Oceanic and Atmospheric Administration’s (NOAA) GOES climate satellites and NASA’s Catalina Sky Survey, which recorded flashes that confirmed the entry of 2024 UQ.
Third Imminent Impression Occasion in 2024
This incident marked the third imminent impactor occasion in 2024. In January, an analogous object designated as 2024 BX1 burned up over Berlin, whereas one other asteroid, 2024 RW1, exploded above the Philippines in September, with footage of the fireball captured by native observers. These situations underscore the rarity but rising frequency of small asteroids getting into Earth’s environment undetected.

World Efforts to Monitor Close to-Earth Objects
Planetary defence stays a precedence as house companies worldwide develop programs to trace doubtlessly hazardous objects. Along with tasks like ATLAS and the Catalina Sky Survey, NASA’s upcoming NEO Surveyor mission goals to make use of infrared expertise to boost detection capabilities. ESA’s NEO Coordination Centre continues its work on monitoring near-Earth objects, whereas deflection experiments, together with NASA’s DART mission in 2022, are additionally underway to check potential asteroid redirection methods.
