An asteroid, dubbed the 'riskiest known to humanity,' was set to strike Earth, but this happened instead

The International Asteroid Day will be observed on June 30, 2022. Asteroid 2021 QM1 had space agencies around the globe in a tailspin in the days leading up to the launch. 

Asteroid strikes posed a real threat from this 50-meter-wide asteroid. Chelyabinsk would have been decimated by an asteroid twice as large as the one that exploded on top of the city.

 As a result of further observations, the risk potential of the asteroid was increased to a point where the European Space Agency (ESA) deemed it the 'most dangerous asteroid encountered by mankind in the last year'. 

The strike date was even given to us on April 2, 2052. But when scientists finally located it recently after being unable to observe the asteroid for months, something seemed different.

An asteroid of the size of the Earth was found by an observatory at Mount Lemmon, Arizona on 28 August 2021. 

NEOs are found almost every night and were not out of the ordinary. Data from telescopes around the world began to signal a disaster, though, and concerns began to grow.

The early observations gave us more information as to the asteroid's path and then we projected the trajectory into the future based on what we knew at the time. 

The trajectory of its future orbits around the Sun could have dangerous implications for Earth in 2052. According to Richard Moissl, Director of Planetary Defense, ESA, the more the asteroid was observed, the greater the risk.

ESA's asteroid risk list isn't a big deal. It is common for initial observations to have some scope of error, but as more data is gathered, the uncertainty shrinks, and the risk factors become smaller. 

However, due to an unfortunate alignment of the planets, it wasn't possible this time. It was impossible to track the asteroid any longer due to the Sun's glare due to its orbital path closer to the Sun. 

ESA had no choice but to wait. However, another risk existed. It might become too faint to detect once the tiny asteroid gets away from the Sun.

However, scientists were able to observe the asteroid for a short period and conduct final calculations before knowing for certain if it would strike the Earth or not. 

A Very Large Telescope (VLT) of the European Southern Observatory was ideally suited for this task. On May 24, it captured a picture of a tiny dot of light using its 8-meter mirror, which was the riskiest asteroid known to mankind. 

For example, in ESA's opinion, the light from 2021 QM1 was 250 million times fainter than the faintest stars visible to the naked eye from a dark spot.

According to the new findings of the observation, it appears to be unlikely that this asteroid will cross paths with the Earth this century at least.
