How Can Asteroids Destroy Our Planet?

We all know the story of the asteroid which made the dinosaurs extinct. But is there a possibility that an asteroid can make humanity have the same fate as dinosaurs, too? Scientists have found the exact ways how.

Windblast

The wind that comes together with the asteroid is the first way. The researchers stated that the wind could rip humans “limb from limb” and tear buildings apart. For this to happen, the asteroid has to measure about 18 meters.

Overpressure

Overpressure is the scientific term used for the shockwave that’s caused when the asteroid just explodes in the air or crashing into the sea, or ground. If this happened, it could knock people down from the ground and break windows and structures. This means that indirect injuries are going to happen because of flying glass. Also, the rupture of internal organs is something to be expected, too.

Thermal radiation

It’s been said that, if an asteroid hits the Earth, a massive fireball will happen. The impact will be devastating for those who are caught in the open when this happens. If the asteroid falls on a city, there’s a possibility that buildings are going to be on fire. However, humans can find shelter in their basements, but if this were to happen, the specific city would be evacuated.

Cratering

We all know that if an asteroid hits planet Earth, it will leave a crater behind. In some cases, the force is so big, that it’s possible that the asteroid can melt instantaneously. But this is very unlikely to happen to you, since you’d already be dead from the overpressure or fried from the fireball. We’re not sure yet which one is worse.

Ejecta

If cratering happens, then lots of rocks and debris happen in the air, too. Some of them could be red hot, so they could start fires in no time, even after the fireball has stopped making us cry. Some can be heavy, and you could get smashed by them in their way.
But this one, just as cratering, is not really important, since you’d already be dead.
