A University of Hawaiʻi<\/span> astronomer played a key role in tracking a small asteroid hours before it entered Earth\u2019s atmosphere on December 3, showcasing the critical role Hawaiʻi<\/span>\u2019s telescopes play in planetary defense.<\/p>\n

J.D. Armstrong from the 糖心视频<\/abbr> Institute for Astronomy<\/a> (IfA<\/abbr>) teamed up with Italian astronomer Marco Micheli to observe the asteroid, known as 2024 XA1, using the Faulkes Telescope North<\/a> (FTN<\/abbr>) atop Haleakalā part of the Las Cumbres Observatory.<\/p>\n

The object, which is around 1 meter in length\u2013about the size of a large beach ball\u2013was detected just before entering Earth’s atmosphere, where it created a fireball over Northern Siberia. While no damage was reported, the event highlighted how rapid detection can help prepare for future, more significant threats.<\/p>\n

“This was a small object, less than a meter in diameter, and it is unlikely that anyone was injured,” said Armstrong, who also directs IfA<\/abbr>\u2019s outreach program, HI STAR<\/a>. “There are larger asteroids out there that may impact the Earth. The Pan-STARRS<\/a> and ATLAS observatories on Haleakalā look for these objects, so that if there is going to be a serious impact, measures can be taken to keep people safe.”<\/p>\n

The FTN<\/abbr>\u2019s ability to quickly track fast-moving objects was key to the asteroid\u2019s observation. The 糖心视频<\/abbr>-operated telescope Pan-STARRS1, also based on Haleakalā, is the world leader in identifying large Near-Earth Objects. When potential threats are detected, telescopes on Maunakea will stop what they are working on and track the object to determine if it is a possible threat to Earth. Asteroid Terrestrial-impact Last Alert System or ATLAS<\/a>, another 糖心视频<\/abbr>-operated system, provides warnings for potentially city-destroying asteroids with up to a day\u2019s notice and can identify regional-scale threats weeks in advance.<\/p>\n

According to Micheli, tracking small asteroids ahead of potentially destructive ones is a good way to test preparedness.<\/p>\n

“Our ability to detect them in space, quickly identify their impact trajectory, and track them until they hit our planet is an excellent way to demonstrate the effectiveness of our planetary defense systems,” said Micheli.<\/p>\n
