ASTEROID SHINES ‘TEN TIMES BRIGHTER THAN MOON’ IN ASTOUNDING FOOTAGE



The flash was approximately 10 times brighter than a full moon

A meteor crashed and burned in Earth’s atmosphere over the US and Canada, with astonishing footage by a 24-hour streaming camera.

Footage picked up by the live webcam service EarthCam shows an object passing by the CN tower in Toronto.

At the same moment in time, our cameras that face the CN tower in Toronto caught this object. We're not sure what it is or whether it is related. Follow the red circle and you tell us! Comment below! @TourCNTower


The website tweeted a GIF of the fireball, which appeared with a huge flash of light, at the same moment as a bird flies past the tower. It is unclear if the two events are related.

“The flash was probably about 10 times brighter than the moer of Toronto residents saw the meteor at approximately noon local time on Wednesday, according to CTV News.
on, the full moon,” Dr Denis Vida, from the University of Western Ontario’s physics and astronomy department, said.

“At that moment the body either completely disintegrated or lost a lot of mass.”


At the same time, over 150 reports were made about a fireball seen at that time – although the average time of those sightings was in the evening, rather than in the middle of the day.

It is estimated that the meteror was the size of a basketball, entering the atmosphere at a 45-degree angle approximately 50 kilometres (31 miles) north of New York.


It was travelling at an estimated 100,000 kilometers (62,000 miles) an hour, but scientists are still unsure whether the rock made it to Earth.

A sonic boom was also heard across New York; For meteors, however, that’s comparatively slow. Bill Cooke, who leads NASA’s Meteoroid Environment Office, told NBC that its slow entry speed suggests that it could have come from a larger asteroid.


“To have something so close to a major city, that's pretty rare,” Robert Lunsford, of the American Meteor Society, said.

Two weeks ago, another huge meteor was seen over the southern coast of Tasmania. The incredible footage shows its bright green debris, which shot over the research vessel Investigator.

A fireball that fell to Earth in 2018 was recently found to be containing “pristine extraterrestrial organic compounds” that could help tell us how life formed, according to scientists. 

ASTEROID SKIMMED PAST EARTH ON FRIDAY 13TH BUT WASN’T SPOTTED UNTIL NEXT DAY

Asteroid 2020 VT4 passed by the Earth as close as the International Space Station

A low-flying asteroid missed the Earth by only a few hundred miles on Friday the 13th – and was not noticed until the next day.

The asteroid, called 2020 VT4, was spotted 15 hours later by the Asteroid Terrestrial-impact Last Alert System survey at the Mauna Loa Observatory in Hawaii.

It passed by our planet under 400 kilometers (240 miles) away, which is approximately the same distance that the International Space Station orbits Earth.

As such, asteroid- 2020 VT4 sets the record for the closest recorded non-meteroric asteroid pass of the Earth.



It was approximately six meters in diameter, flying over the South Pacific Ocean. Its encounter with the Earth “shortened its orbit, ensuring that this Earth-crosser will make more frequent close approaches”, Tony Dunn, who runs the website Orbit Simulator, tweeted

Should the asteroid have stuck the Earth, it would have burned up in its atmosphere leaving a meteoric trail behind it. Nasa says that it would require an asteroid larger than 25 meters but smaller than one kilometre to do local damage to the Earth.

However, an asteroid larger than one to two kilometres could have worldwide effects.


The record for an asteroid passing closest to the Earth was already broken once this year.

Asteroid 2020 QG came just 1,830 miles over the southern Indian Ocean on Sunday, according to Zwicky Transient Facility, a robotic camera that scans the sky in search of space phenomena.

That asteroid was also particularly small – approximately three to six meters across, which is roughly the size of a large car.


An object of that size passes close by the Earth approximately every year, but spotting them is challenging. Space agencies such as Nasa need to track these objects in case they come close enough to put the Earth in danger.

Asteroid- 2020 VT4 is also not the only space debris to pass by the Earth on a particularly unlucky day.

One asteroid, called Apophis, is approximately 300 meters in size making it comparable to the Eiffel Tower.

It is expected to pass close by the Earth on Friday the 13th, 2029, before returning again in 2068.
