In films such as 'Armageddon' and 'Deep Impact,' cinematic portrayals of asteroids striking Earth often leave viewers questioning the real-world implications of such catastrophic events, especially if they were to occur near their own cities or towns.

NASA considers all possibilities

Even though it might seem like something we don't need to worry about, there are some people that have to consider these possibilities. Some at NASA take this possibility very seriously.

DART mission

In 2022 humanity had its first attempt at knocking an asteroid off course with a spacecraft. NASA's DART mission was to test whether we could defend our planet from a cosmic crash.

Every day, space agencies track the solar system to survey the hundreds of thousands of asteroids that cross it, paying close attention to calculate if any of them could collide with our planet.

Neal Agarwal has recreated several scenarios on an Asteroid Simulator on his website Neal.fun. It demonstrates the consequences of an asteroid collision anywhere in the world.

An adaptable simulator

Have you ever though about what would happen?, NASA considers all possibilities, DART mission, Under constant surveillance, What could happen if an asteroid hits the Earth?, An adaptable simulator, Choose area and launch, Science-based simulation, Specific and extensive data, Derivated consequences, Want to see an asteroid hit your city?, New York City, Mexico City, Sao Paulo, Hong Kong, Nairobi, Kenia, A fun yet disturbing tool

The simulator allows you to choose the type of asteroid: iron, stone, gold, carbon, or a comet (made of ice). You can program its diameter between 3ft and 1 mile. It also has different speed options ranging from 1.000 mph to 250.000 mph or the angle of impact.

Choose area and launch

Finally, the user only has to choose a point on the map to launch the asteroid. The simulator will then animate several different results, from the size of the crater to the resulting earthquake's magnitude.

The simulation is based on the research of Dr. Gareth Collins and Dr. Clemens Rumpf, who specialized in studying asteroid impacts. The results are reliable and an excellent source for learning about the universe.

Specific and extensive data

Like an atomic bomb, an asteroid event creates different waves and consequences upon impact: a crater, followed by a fireball, a shockwave, intense winds, and earthquakes. The simulator measures all of them and provides data on the number of deaths and the affected radius.

Derivated consequences

In every category, the simulator explains the derivated consequences of each event, whether the direct impact and crater create a tsunami or the shock wave collapses buildings.

This list shows examples of how it would look if an asteroid hit certain cities. For the demonstration, the simulator launched a mile-long gold asteroid at a speed of 250.000 mph.

New York City

More than 13 million people would vaporize in the crater if an asteroid this size hits New York City. However, the total aftermath would result in hundreds of millions of deaths. The shockwave would reach the Dominican Republic in the south, Dallas in the west, and Hudson Bay (Canada) in the north.

If this fireball of an asteroid were to strike in Mexico City, it would kill more than 40 million people. It could reach most of the country and Honduras in the south.

When the simulator targets Dallas, on the other hand, it shows a shockwave that would affect most of North America, practically destroying all the buildings and houses in the US and Mexico.

If an asteroid were to hit the coast of Sao Paulo, the resulting shock wave would destroy most South America. It would cause a 1.1-mile-tall tsunami, on top of vaporizing almost 3 million people in the crater.

Tokyo
