Some of the worrying questions that weigh on the minds of scientists, astronomers in addition to most of the 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 again and again. Now, a NASA scientist has tried to place all hypothesis to relaxation. In a video shared on YouTube, asteroid knowledgeable Davide Farnocchia, of the Jet Propulsion Laboratory, mentioned there was no asteroid risk to Earth when it comes to affect hazard.
The caption of the video reads, “Is NASA conscious of any Earth-threatening asteroids? Fortunately, there aren’t any identified asteroid threats to Earth for at the very least 100 years. However that does not imply we’re not trying.” NASA goes on so as to add that “asteroid knowledgeable Davide Farnocchia of our NASA Jet Propulsion Laboratory breaks it down”.
“There is no such thing as a asteroid that we all know of that’s regarding when it comes to affect hazard,” Farnocchia says, Asteroid impacts have occurred prior to now and might occur sooner or later too. However Farnocchia mentioned that these have been “uncommon occasions”.
“An asteroid affect that would trigger severe regional harm solely occurs each few thousand years and even longer. Nonetheless, it is a good suggestion to guard us towards that risk, and the rule of the sport is locate the asteroid earlier than they discover us,” Farnocchia added.
He additional states that because of this NASA has been funding search programmes for greater than 20 years to “observe the sky just about each single evening to search out and observe asteroids”.
To date, the US area company has found over 1,000,000 asteroids, together with 95 p.c of the asteroids which might be higher than a kilometre and will come near the Earth.
Farnocchia added that after NASA scientists uncover an asteroid, they venture its movement into the long run to search out out if there is a risk of a collision with the Earth. They rank every asteroid on a risk-ranking scale, referred to 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 up to now, the Torina scale is zero. Which means “lowest threat for the subsequent 100 years”, he added.

In line with a NASA ‘Did You Know’ explainer, the “highest threat of affect for a identified asteroid is a 1 in 714 probability of affect by an asteroid designated 2009 FD in 2185, which means that the chance that it might affect then is lower than 0.2 p.c”.
One other asteroid NASA is intently monitoring is known as Bennu. It has a 1/ 2,700 probability of impacting Earth between 2175 and 2195.
