Lately, more and more asteroids have come close to Earth on their journey in our Solar System and our universe. The most recent example is asteroid 2019 OK which was observed by astronomers with only a few hours before it hurtled by Earth with a speed of 40,000-50,000 mph the closest than any other asteroid, at 40,000 miles distance from our home planet.
2019 OK is around 300 feet and is two times bigger than the asteroid that destroyed everything for 800 square miles in Siberia a little more than 100 years ago. It is worth mentioning that the asteroid in Siberia has not even touched the ground, but blew up in the air. Regardless, the force of the explosion was so strong that 80 million trees and other plants had been knocked down to the ground.
If 2019 OK would have entered the atmosphere and hit the ground, a region of more than 2,000 square miles would have been destroyed. The reason the asteroid was not observed earlier was that it was obscured by the sun.
Researchers Should Try Finding Ways To Prevent An Asteroid Impact
There was another instance this year in which another unidentified asteroid blew up over the Pacific Ocean. The power of the explosion was 10 times bigger than the nuclear bomb that destroyed Hiroshima. This time we were lucky, but maybe someday in the future, a slight oscillation in an asteroid’s orbit would cause the celestial body to head towards our planet.
As of now, there are five asteroids that astronomers have discovered and are headed in our direction and many others that orbit around the Earth or other planets in our Solar System. Most of them have been discovered, but there are some that were not. All have the ability to destroy at least an entire city, not to mention to kill millions of human beings and other living beings.
Unfortunately, not even with all the innovative technology, the space agencies have not been able to come up with a technology that could prevent an asteroid collision and the destruction of Earth.
