A small asteroid designated CERNQ52 is scheduled to impact Earth's atmosphere near northwest Australia today at 16:07 UTC. [^1]

The object, which measures between 0.6 and 1.2 meters in diameter, was discovered by the Mount Lemmon Observatory as part of the Catalina Sky Survey. [^3][^4]

Adrien Coffinet, a member of the Minor Planet Mailing List, noted that this event will be the first time an Aten asteroid was detected in space before impact, whereas previous impactors were Apollo asteroids. [^5]

Due to its small size, the asteroid is expected to disintegrate largely upon entering the atmosphere and produce an extremely bright meteor known as a fireball. [^6]

The International Meteor Organization issued an alert regarding the atmospheric entry of asteroid CERNQ52 over the Indian Ocean around 16:35 UTC. [^7]
