7 terrifying ways an asteroid could eradicate life on our planet

It is believed that an asteroid extinguished the dinosaurs – but another blow from a massive space rock could trigger the demise of humanity.

Now Scientists Have Explained Exactly How an Asteroid Could Work Kill those people who are unfortunate enough to get caught under one, if – or if – they hit the ground.

How can asteroids kill us seven different species?

University of Southampton researchers have identified seven different risks of asteroid collision.

They published a paper discussing "asteroid impact effects and their immediate dangers to human populations" on the same day, when an asteroid the size of the Rock of Gibraltar was uneasily zoomed in close to Earth.

The team used computer simulations to estimate the risk of 50,000 different sizes of asteroid.

Their study found that asteroids caused much more death and destruction when they hit the ground or in the sky a mass of land exploded in an "airburst" rather than plunging into the sea and causing a tsunami.

"The analysis of the average number of accidents per impactor [asteroid] shows that there is a significant difference in the expected loss for air blast and surface impact and that the average impact over land is an order of magnitude more dangerous than one above water," the source wrote Team.

As expected, the researchers also found that larger asteroids pose a greater risk than smaller ones. 19659006] Space rocks that were smaller than about 40 meters in diameter, but exploded in a puff of air, which represented a different kind of risk for humans.

The 4 Vesta asteroid is so large that it can be up to date

With a diameter of 326 miles, it is 50 times wider than the meteor that destroyed the dinosaurs.

The largest crater is 285 miles in diameter.

Although don't worry that particul An asteroid is not expected to hit the earth.

They identified seven different ways in which space rocks could cause "loss of life," which we have listed below.


The wind was created as an asteroid that is thrown into the earth or explodes in an air blast is the "most critical impact effect".

Any gusts caused by an asteroid impact are likely to be so severe that they "scrape off" bodies and objects to cause damage.] The wind caused by a large space rock would rip people limb by limb and knock down buildings on them.

An asteroid only needs to be 18 meters wide to cause losses in this way, the researchers found.


This is the scientific term for the shock wave that occurs when an asteroid explodes in the air or crashes into the ground or into the sea.

This effect caused injuries when a meteor exploded in the sky over the Russian city Chelyabinsk

The researchers wrote: "Most damage The injuries and injuries during this event were caused by the aerodynamic shock that hit people to the ground and damaged Structures and windows struck and caused indirect injury from flying glass splinters. "

Overpressure can also" break internal organs "

The asteroid is large enough that overpressure would effectively tame the victims' inside.

Thermal Radiation

When an asteroid hits our planet, it will cause a massive fireball.

The Implications Of It Will Probably Be Devastating To Everyone (19659006) When the asteroids hit or explode over a city, buildings are likely to be set alight – with larger asteroids causing fireballs that are miles wide.

While humans would be able to protect themselves from the fireballs caused by smaller reservoirs in cellars, the risks of a larger object are so great that cities would have to be evacuated if there was a risk of asteroid impact

] Crater Formation [19659018] When an object hits a planet, it usually causes a massive crater.

Sometimes the power is so great that the asteroid immediately melts away.

However, the risk is likely to be fairly low unless you are unlucky enough to be in exactly the area where the crater was formed.

But by the time the crater was formed, you would probably have been torn to pieces by the overpressure or burned in a fireball.


The process of cratering is likely to throw a huge amount of rocks and debris into the air.

Some of these fragments are likely to be glowing, which means they could light more fires even after a fireball died down.

Others They will be very heavy, meaning that they would crush anyone who gets in their way.

Both the ejecta and the crater, however, are considered to be low, as humans would have been killed by the other effects of an asteroid impact

Object is large enough, but it would sen d) material that flies into the air and the sun could block.

If this material stayed in the atmosphere long enough, plants would die and slowly starve to death on Earth.


If an asteroid thrown into the ocean, it would inevitably trigger a massive wave.

This has the potential to kill people far enough away from the asteroid to be safe from fireball and over-pressure.

But a tsunami wave takes quite a long time to spread across a great ocean, giving people the opportunity to save themselves by advancing into higher areas.

"Tsunamis can only reach offshore populations because their range is limited to a few kilometers," the researchers added.

They found that tsunamis pose a lower risk than previously thought.

Seismic Trembling

An impact of the asteroid would likely cause an earthquake.

But quakes are only considered a "minor effect" the number o (19659006) The asteroid is unlikely to cause the same kind of devastation caused by the kind of natural disasters known to man.

If you're far enough away from the asteroid, you do not have to worry about being burned alive or being torn to pieces, you probably do not have to worry about earthquakes that dump your house on you.
