What would happen if an asteroid hit Earth today?

An asteroid is not expected to crash into Earth at some point, but space agencies are keeping an eye on them for safety.

Depending on the size of the space cliff, an asteroid impact could be an extinction-level event, and scientists have made simulations to see how bad it could be.

If you’ve seen the Netflix movie Don’t Look Up, you may be worried about potential asteroid impacts.

But not all asteroids would mean the end of humanity.

The space rock had to be pretty big to kill us all.

Scientists believe the asteroid that wiped out the dinosaurs was about 7.5 miles wide.

If an asteroid of that size hit Earth today, things would instantly change because of the force of the impact and its impact on the environment.

Experts believe we will experience fires, shock waves, heat radiation, a large crater, acid rain and giant tsunamis if the asteroid hits the water.

Britt Scharringhausen, associate professor of physics and astronomy at Beloit College, told Inverse: “All the ash from the fires and all the finer grains from the impact will hang out in the atmosphere for a long time, and we get what’s called an effect winter.

“It’s going to block sunlight, and all the ash that falls into the ocean is acidifying the top layers.

“So you burn things, kill everything in the ocean and freeze the Earth, and it goes through about two years of constant winter.”

Scharringhausen does not believe that all life on Earth would die after a large asteroid impact.

Some small creators survived the asteroid attack that killed the dinosaurs.

If people took the right precautions, it is possible that they too could survive.

Scharringhausen explained: “Not everything will die. If we think of humans, the way to survive would be to get underground.

“You might be able to ride it out in a bunker if you have the supplies to cope with the winter period when you can not grow any edible food.

“Maybe the picky crops that people like to grow will not get through it as well, but there is seed storage, so if they are well protected enough, you can get agriculture restarted.”

Plans to save Earth from asteroids

Some experts are concerned that Earth is not yet ready to defend itself against potentially deadly asteroids.

SpaceX CEO Elon Musk once raised concerns by tweeting: “a large rock will hit Earth eventually, and we currently have no defense.”

However, Nasa is investigating some defense methods.

It recently launched its Double Asteroid Redirection Test mission.

Nasa said: “DART is the first mission ever dedicated to investigating and demonstrating a method of asteroid deflection by altering the motion of an asteroid in space through kinetic influence.”

The DART vessel was to collide with a small asteroid called Dimorphos in September with the aim of moving it off course.
