A small asteroid named CERNQ52 is expected to enter Earth's atmosphere over the Indian Ocean at 16:35 UTC on September 6, 2026. [^3]

The object measures approximately 80 centimeters in diameter and was detected on September 6, 2026. [^1] Richard Moissl, head of Planetary Defense at the European Space Agency, stated the asteroid is harmless and will likely produce a bright meteor upon entry. [^2]

CERNQ52 could be the first Aten-type asteroid detected in space prior to its atmospheric entry. The fireball may be visible from areas near northwestern Australia, where it will be night at the time of entry. [^7]

Small fragments of the asteroid may survive the passage and reach the surface as meteorites, with much of any surviving material likely ending up in the ocean. [^5] Estimates place the atmospheric entry between approximately 12:00 p.m. and 12:35 p.m. Puerto Rico time on September 6. [^6]
