What would happen if a huge asteroid crashed in Lima? This website simulates it

Asteroid Launcher is a disaster simulator: it allows you to know the consequences of an asteroid falling in any city in the world.


A collision of an asteroid against the planet can be catastrophic: it can destroy everything from small cities to, as happened millions of years ago, mark the extinction of living beings.

For this reason, NASA and more space agencies are preparing to protect themselves from this type of situation, in missions such as DART that seek planetary defense . But there are some projects like Asteroid Launcher that, on the contrary, try to show the consequences of these emergencies.

What would happen if an asteroid crashed into your city?

Asteroid Launcher ‘s mission is to provide data on the range of an asteroid impact depending on its size and weight on different cities.

It was created by Near Agarwal and you can enter to “play” with her at this link.

The portal provides a world map from where we can choose the city where you want the asteroid to crash . On the star, we can choose its composition, its diameter and its speed and angle of impact.

For example, if a rocky asteroid 500 meters in diameter crashed into RPP Noticias in Lima at a speed of 20 kilometers per second, it would leave a crater 7.8 kilometers in diameter with a depth of 546 meters.

The curious thing is that the proof does not stop there.

In our example, the platform indicates that the impact would be the equivalent of 8 gigatonnes of TNT and would release more energy than in a hurricane. Only in the crater would die vaporized about 300 thousand people.

The strong thing is the rest of the consequences in this regard. From the fireball, more than 11,000 people would receive third-degree burns, plus another 15,000 would suffer second-degree burns. Nearly 6 million people could lose their lives.

Trees would catch fire 111 kilometers from impact.

Asteroid Launcher continues to spit out data and states that 2 million people would die from a 243 decibel shock wave.

People within a 24-mile radius could have lung damage, while anyone within a 32-mile radius would have ruptured eardrums. Houses within 117 km would collapse.

More than 700,000 people would die from 4 km/s wind gusts, which would be faster than storms on Jupiter. Nearly all trees within a 126 km radius would be felled.

Finally, the impact would cause a magnitude 7.1 earthquake, which could leave more than 9,000 dead and would be felt 220 kilometers away.

The end of humanity?

To end life on Earth, it is estimated that an asteroid would have to be 96 kilometers wide. Asteroid Launcher is unable to simulate a real astro in these conditions.
