A small space rock was detected just hours before it was to crash into Earth’s atmosphere and land in Canada’s Lake Ontario on Saturday (November 19).
thumbnail-asteroidwhich is less than 3 feet (1 meter) wide, was spotted by astronomer David Rankin at the Mount Lemon Observatory in Arizona, according to SpaceWeather.com (Opens in a new tab). Subsequent observations by other astronomers confirmed that the rocks were coming from a direction main asteroid belt between orbits Mars And the Jupiterwas on a collision course with a land.
Just three hours after the first detection, the object, dubbed C8FF042, cut through the skies over Canada and landed in Lake Ontario. According to NASA (Opens in a new tab).
According to the European Space Agency (ESA), this was Only the sixth case From an asteroid that was found just before the impact. in MarchA galactic astronomer discovered a somewhat larger space rock just two hours before it burned up over the North Atlantic Ocean.

Witnesses in and around Toronto reported seeing a bright fireball that lit up the sky Saturday around 3:27 a.m. EDT (0827 GMT). Many meteors and webcams have captured views of the fireball; One amazing video shows a streak of light passing behind the famous CN Tower in Toronto.

According to NASA, radar stations tracked the meteor from about 9 miles (15 kilometers) high to 0.53 miles (0.850 kilometers) high, where it likely fragmented. Space agency officials wrote that most of the fragments may have fallen into Lake Ontario, with some smaller pieces possibly landing near the towns of Grimsby and McNab. American Meteorite Society (Opens in a new tab) 59 reported fireball sightings.
Small asteroids frequently cross the path of our planet. The smallest ones usually burn Earth’s atmosphere, leaving behind only ephemeral streaks of light. Large rock fragments can hit the precious ground meteorites Scientists can study them to get a glimpse into the nature of the organisms in Solar System.
Larger boulders, more than 65 feet (20 m) wide, can cause problems on the ground as the shock waves from their explosions can shatter windows and destroy trees. Larger asteroids can be more damaging, but impacts are fortunately very rare.
The international astronomy community is mapping the near-Earth asteroid population with the goal of keeping track of all potentially hazardous asteroids. Astronomers believe that most of the “planet killers” – objects larger than 0.6 mile (1 km) across – are already known and none of them pose an immediate danger. However, many small rocks capable of causing damage across the country remain undiscovered.
In September this year, NASA’s DART probe It collided with a small asteroid, Dimorphos, with the intention of changing its orbit around the parent asteroid, Didymus. The experiment was successful, as it proved that if a future threat was detected in advance, we might be able to deflect it.
