Is NASA aware of any asteroids threatening Earth? [Video]


He is NASA Are you aware of any asteroids threatening the Earth? Fortunately, there have been no known meteorite threats to Earth for at least 100 years. But that doesn’t mean we don’t look. Asteroid expert David Farnokia of NASA’s Jet Propulsion Laboratory dismantled them:؟v=W54-IDHg5Fs

Is NASA aware of any asteroids threatening Earth? We asked a NASA scientist.

No, there is no asteroid that we know of that is related to impact hazards.

Now, we know that asteroid collisions happened in the past and could certainly happen in the future. But we must bear in mind that these are rare events.

An asteroid impact that could cause serious regional damage occurs every few thousand years or more.

However, it is good to protect us from this possibility and the rule of the game is to find the asteroids before they find us.

That’s why for more than 20 years, NASA has funded research programs to observe the sky nearly every night to find and track asteroids.

And we did a good job at that. So far, we’ve discovered more than one million asteroids, including 95 percent of the asteroids over one kilometer long that can approach Earth.

Once we detect an asteroid, we display its movement in the future to assess the possibility of it colliding with Earth.

We have a scale called the Turin Scale that helps us rank the hazards coming from each asteroid. It goes from zero, which is the lowest risk, to 10, which is the highest risk.

The good news is that for all the asteroids we’ve discovered so far, the Turin scale is zero – so it’s the least dangerous for the next 100 years.

So, is NASA aware of any asteroids threatening Earth?

No. But we will continue to search the sky in anticipation.
