The European Space Agency said the event marked only the sixth time in history the impact of a space object with Earth was successfully predicted.

The agency said while most asteroid collisions with Earth are only discovered after the fact from evidence like craters, the number of occasions in which a space rock is detected before it strikes is growing.

The Minor Planet Center, which monitors asteroids, said a fast-moving object was detected by the Mount Lemmon Survey near Tucson, Arizona, triggering a "warning of an imminent impact.".

Mike Hankey of the American Meteor Society told The New York Times its possible meteorites — debris from a space object — from Saturday's event could be discovered near Niagara Falls
