Asteroids flying past Earth, even big ones, are now more common than before — especially since Nasa’s jet propulsion laboratory (JPL) can track these celestial objects.
Scientists believe that it’s only a matter of time before one of them eventually gets pulled into the Earth’s orbit .
That being said, it’s unlikely that anyone of them will be as catastrophic like the one that wiped out the dinosaurs, but it may still be able to take out a whole city.
Last week, an asteroid the size of the Empire State Building passed 4.6 million miles from Earth but could’ve been 500 times more destruction than the atomic bomb that fell on Hiroshima had it actually hit.
Today, another asteroid the size of the Great Pyramid of Giza is going to skim by. On September 6, Asteroid 2019 GT3
— bigger than Giza and the Empire State Building — is expected to pass by Earth as well.
Point being, these ‘near misses’ have become all too common. Nasa’s JPL tracks these objects to monitor them — not out of fear of collisions. But, considering their frequency, scientists believe it’s only a matter of time before one of them gets pulled in by Earth’s gravity and plumments onto our planet’s surface.
But, here’s the thing. Anything like the 7.5 mile wide asteroid that hit Earth and took out the dinosaurs hasn’t been spotted on any radar .
According to Nasa, at least 95% of asteroids have been catalogued and none of pose a direct threat to Earth. But that doesn’t mean they are completely benign. They might not wipe out Earth but some of them do have the power to destroy entire cities
