In the early hours of Saturday, Nov. 19, the skies over southern Ontario, Canada, lit up as a tiny asteroid harmlessly streaked across the sky high in Earth's atmosphere, broke up, and likely scattered small meteorites over the southern coastline of Lake Ontario. The fireball wasn't a surprise. Roughly 1 meter (3 feet) wide, the asteroid was detected 3 ½ hours before impact, making this event the sixth time in history a small asteroid has been tracked in space before impacting Earth's atmosphere.

NASA is tasked with the detection and tracking of much larger near-Earth objects that could survive passage through Earth's atmosphere and cause damage on the ground, but those objects can also be detected much further in advance than small ones like the asteroid that disintegrated over southern Ontario. Such small asteroids are not a hazard to Earth, but they can be a useful test for NASA's planetary defense capabilities for discovery, tracking, orbit determination, and impact prediction.

I lived in Toronto for about a year (interestingly, it was during tye whole Rob Ford thing).

I have some friends there I will be sorry to lose, but other than that not much loss.

People fail to realize the size of the Earth...
100 miles of atmosphere is nothing compared to how large our planet truly is...
Which is why Nasa has to splice together photo’s to show us...

Ontario area has been hit in the past. There is big mining going on mining that meteor that crashed there about 1.8 billion years ago.
