Small Asteroid Detected Before Exploding Over Australia's Waters
A very small space rock called 2026 RW1 came toward Earth on September 6, 2026.
Scientists spotted it before it reached our planet.
It entered the atmosphere near northwestern Australia and burned up over the Indian Ocean.
The rock was about as wide as a small person is tall.
It was too small to hurt people or buildings.
Scientists said this was only the 13th time they had found a space object before it arrived.
Events like this help scientists practice finding and tracking larger, more dangerous asteroids.
The event acted like a safe test of Earth’s asteroid-warning systems.
Object 2026 RW1 entered Earth’s atmosphere northwest of Australia on September 6, 2026.
The roughly 0.8-meter object burned up over the Indian Ocean and posed no threat.
Scientists said it was only the 13th small object detected before impact.
The Catalina Sky Survey reported the object, with earlier detections by Pan-STARRS.
NASA and the European Space Agency used the event to test planetary-defense tracking and warning systems.
- Who
- NASA, the European Space Agency, the Catalina Sky Survey, Pan-STARRS, and other planetary-defense teams monitored the object.
