Do you remember the movies Deep Impact and Armageddon? Both were about enormous space objects heading for the earth with the potential to destroy the planet.

In one of the movies, disaster is averted thanks to some heroes who break up the object. In the other, a piece of the object crashes into the earth wiping out New York City as well much more and killing millions.

NASA is now saying that this is a potential reality for us.

According to Brobible,

NASA is giving everyone plenty of time to prepare for a potential asteroid collision with the Earth. Astronomers have provided the exact date that a city-killer asteroid the size of the Great Pyramid of Giza could potentially smash into Earth.

Asteroid JF1 is heading towards our planet, and there is a slight chance that the space rock could collide with Earth. The asteroid has a diameter of over 420 feet or roughly the size of the Great Pyramid of Giza in Egypt…

There is a one in 3,800 chance the asteroid will hit Earth on that day, according to NASA…

If JF1 smashes into Earth, the impact will release 15 kilotons of TNT, which would be more than 15 times larger than the atomic bomb that decimated Hiroshima in 1945.

An asteroid of this size is classified as a “city-killer” because the space rock is large enough to pierce through the atmosphere without breaking up and obliterate an entire city. If the asteroid missed the land and splashed down in the ocean, it could unleash a powerful tsunami that could kill a large number of people.

We have plenty of time to act. This includes sending some sort of explosive device to try and break up the asteroid, we could potentially land something on it and steer it off course, or maybe it will miss us completely.

I thought this video was pretty cool as well. It shows a simulation of what could happen using the Universe Sandbox Simulation program.
