According to the International Meteor Organization and the European Space Agency, a small asteroid designated as CERNQ52 is set to harmlessly enter Earth’s atmosphere over the Indian Ocean near northwest Australia on September 6, 2026, between 16:00 and 16:30 UTC. Measuring less than 1 meter across, the object was discovered by the Mount Lemmon Observatory survey and is expected to produce a bright meteor flash visible in the night skies of the region.
Discovery and Trajectory of Asteroid CERNQ52
According to Richard Moissl, the Head of Planetary Defense for the European Space Agency, automated tracking systems calculated an atmospheric entry window between 16:00 and 16:30 UTC for the roughly 0.8-meter-wide object. Moissl confirmed via social media that the impact would occur northwest of Australia over the ocean.

Adding to the scientific significance of the event, Adrien Coffinet of the Minor Planet Mailing List noted that CERNQ52 represents a rare classification. According to Coffinet, this marks the first Aten asteroid—an object with an orbit strictly under 1 astronomical unit—detected in space prior to hitting Earth. Previous pre-impact detections involved Apollo asteroids, which maintain wider orbits farther from the sun than Earth.
Did you know? Aten asteroids have orbits smaller than Earth’s average distance from the sun (1 AU). Detecting one before atmospheric entry provides planetary defense researchers with crucial data on smaller near-Earth objects.
What Observers Can Expect Near Northwest Australia
Because the atmospheric entry window falls between 16:00 and 16:30 UTC, local skies in northwest Australia will be dark. According to survey reports, this timing increases the chances that residents in the area might spot a bright flash of light as the meteor burns up. Experts emphasize that the object poses no danger to people on the ground.
The International Meteor Organization issued an official alert regarding the trajectory over the Indian Ocean. Observers who happen to catch a glimpse of the flash are encouraged by space agencies to submit reports and photographic evidence to scientific databases to help researchers refine impact prediction models.
Frequently Asked Questions
Is Asteroid CERNQ52 dangerous to Earth?
No. According to the European Space Agency, the object measures roughly 0.8 meters in diameter and will harmlessly burn up in Earth’s atmosphere.
When and where will the impact happen?
The atmospheric entry is scheduled for September 6, 2026, between 16:00 and 16:30 UTC, occurring over the Indian Ocean northwest of Australia, as reported by ESA planetary defense officials.
What makes this asteroid detection unusual?
According to Minor Planet Mailing List contributor Adrien Coffinet, CERNQ52 is the first Aten asteroid detected in space before impacting Earth, distinguishing it from previously detected impactors that belonged to the Apollo group.
