Is Earth Under Threat From Asteroids? This is What a NASA Expert Had to Say

Some of the worrying questions that weigh on the minds of scientists, astronomers in addition to most people is whether or not the Earth is threatened by a possible asteroid collision? Regardless of being addressed by the scientific group, this query crops up repeatedly. Now, a NASA scientist has tried to place all hypothesis to relaxation. In a video shared on YouTube, asteroid professional Davide Farnocchia, of the Jet Propulsion Laboratory, stated there was no asteroid risk to Earth by way of influence hazard.

The caption of the video reads, “Is NASA conscious of any Earth-threatening asteroids? Fortunately, there are not any identified asteroid threats to Earth for not less than 100 years. However that does not imply we’re not wanting.” NASA goes on so as to add that “asteroid professional Davide Farnocchia of our NASA Jet Propulsion Laboratory breaks it down”.

“There isn’t a asteroid that we all know of that’s regarding by way of influence hazard,” Farnocchia says, Asteroid impacts have occurred up to now and may occur sooner or later too. However Farnocchia stated that these have been “uncommon occasions”.

“An asteroid influence that might trigger critical regional injury solely occurs each few thousand years and even longer. Nonetheless, it is a good suggestion to guard us towards that chance, and the rule of the sport is locate the asteroid earlier than they discover us,” Farnocchia added.

He additional states that this is the reason NASA has been funding search programmes for greater than 20 years to “observe the sky just about each single night time to seek out and observe asteroids”.

Up to now, the US area company has found over one million asteroids, together with 95 % of the asteroids which might be better than a kilometre and will come near the Earth.

Farnocchia added that after NASA scientists uncover an asteroid, they challenge its movement into the long run to seek out out if there is a chance of a collision with the Earth. They rank every asteroid on a risk-ranking scale, known as Torino scale. “It goes from zero, which is lowest threat, to 10, which is highest threat,” he says.

The excellent news is that for all of the asteroids NASA has found to date, the Torina scale is zero. Which means “lowest threat for the subsequent 100 years”, he added.

Watch the video right here:

In accordance with a NASA ‘Did You Know’ explainer, the “highest threat of influence for a identified asteroid is a 1 in 714 probability of influence by an asteroid designated 2009 FD in 2185, which means that the likelihood that it might influence then is lower than 0.2 %”.

One other asteroid NASA is carefully monitoring is known as Bennu. It has a 1/ 2,700 probability of impacting Earth between 2175 and 2195.
