Large asteroids approaching Earth don’t represent anything new, but luckily for us, they’re surely very rare. Many of the space rocks that come too close get obliterated in the atmosphere due to air friction. However, exceptions will indeed occur, and NASA cannot possibly keep an eye on the entire sky.
According to USA Today News, a few asteroids that are even larger than the Great Pyramid of Giza will approach Earth in the following weeks. For those unaware, the Egyptian tomb has a height of 138 meters.
No reason to worry
If you’re hoping for the world to end in 2021, you can count on something else to get the job done. The asteroids will pass by our planet, which means that there’s no need to worry.
But what if an asteroid capable of mass destruction will really pay us a visit someday? Astronomers keep looking for solutions, and one idea is simply to fire nukes at the space rock in order to blow it to bits.
However, Neil deGrasse Tyson, one of the most famous astrophysicists in the world, is clearly not a fan of the idea of blowing up such an asteroid. He said as quoted by RawStory.com:
So, if you look in movies about this sort of thing, what they want to do is blow the sucker out of the sky,
We’re very good at blowing stuff up because we have no end of weaponry to do this. But that’s not the wisest path. All engineering calculations tell us if you blow something up, while we’re good at blowing it up, we’re not as good knowing where the pieces will end up. So, it’s safer and it’s more controlled to deflect an asteroid from harm’s way.
