  • A fireball lit up a neighborhood and passed over Toronto early Saturday morning.

  • The impact of the object on the Earth was predicted, which was the sixth time in history.

  • The European Space Agency said such technology for detecting small objects is improving.

A vibrant fireball that flashed across the night sky in the early hours of Saturday morning passed over the skyline of Toronto, Canada, before colliding with Earth near Niagara Falls.

The fireball was captured in several videos, including one which showed as if passing by the city’s CN Tower.

Others videocaptured by a security camera at the home’s front door, showed the fireball lighting up the entire sky over the neighborhood before zooming out.

The European Space Agency said that this event marked only the sixth time in history that the impact of a space object on Earth was successfully predicted. The agency said that while most asteroid collisions with Earth are only detected after the fact based on evidence such as craters, the number of cases where a space rock has been detected before it hits it is growing.

In fact, all six detections have occurred since 2008, according to ESA, which said continued improvements to sky-scanning telescopes are likely to make detections of the smaller objects — which often hit Earth — more common.

On the other hand, large asteroids are much easier to spot.

Saturday’s fireball was expected by amateurs and professional astronomers hours before it hit. The Minor Planet Centerwhich track asteroidssaid the fast moving object Mount Lemmon Survey near Tucson, Arizona, prompting an “imminent impact warning”.

The MPC said seven observatories were able to spot the object before it entered Earth’s atmosphere around 3:27 a.m. ET over Brantford, Ontario. According to ESA, the object was less than 1 meter.

The term fireball is used to refer to extremely bright meteors, commonly called shooting stars, that can be seen over a wide area. “Objects that cause fireballs are usually not large enough to survive passage through the Earth’s atmosphere intact, although fragments or meteorites are sometimes found on the ground,” he says. NASA.

Mike Hankey of the American Meteorological Society said The New York Times its possible meteorites – debris from a space object – from Saturday’s event could be detected near Niagara Falls.
