SCIENTISTS have unveiled an Armageddon-style plan to fire nukes at asteroids that may be considered a threat to Earth.

The Hollywood-esque plot suggests detonating a nuclear bomb roughly a mile away from the space rock to help knock it off course.

nasa 's asteroid watch list lists the most dangerous asteroids that could hit earth in future — Space rocks are still a risk to life on Earth, which is why researchers are throwing their weight behind upping our planetary defences

Scientists believe the explosion, and the blast of X-ray radiation that comes with it, could be enough to deflect an oncoming impact.

“The vaporised material shoots off one side, pushing the asteroid in the opposite direction,” said Dr Nathan Moore, the first author on the new study from Sandia National Laboratory.

“It’s like turning the asteroid into its own rocket.”

It comes just a week after fears of a collision with city-killer asteroid Apophis, nicknamed ‘God of Destruction’, were reignited.

Apophis is scheduled to make an intimidatingly close flyby of Earth on Friday 13, 2029.

The near-Earth object is expected to pass around 19,800 miles (32,000km) of Earth, closer than some satellites, where some stargazers may be able to see it with the naked eye.

No asteroid is expected to come as close for a few thousand years.

And if Apophis is hit by other space rocks on its journey around the solar system, there is a one in a billion chance it’s path may be diverted to collide with Earth.

Now, those are still pretty good odds.

But scientists are well aware that cataclysmic asteroid strikes are not reserved for the dinosaurs, and the dinosaurs alone.

Earth's closest near-misses

One of Earth's closest near-misses occurred only a few years ago.

Asteroid VT4, which is estimated to be just five to 10 metres in diameter, came as close as 383 km to Earth’s surface in 2020.

Another close encounter happened on 31 March 2004, when meteoroid FU162 zoomed past just 6500km above Earth’s surface.

Asteroid Apophis is roughly double that, and is wide as the Eiffel Tower is long.

While the rock that took out the dinosaurs 66million years ago is believed to have been six miles wide.

What's the difference between an asteroid, meteor and comet?

Here's what you need to know, according to Nasa...

Asteroid: An asteroid is a small rocky body that orbits the Sun. Most are found in the asteroid belt (between Mars and Jupiter) but they can be found anywhere (including in a path that can impact Earth)
Meteoroid: When two asteroids hit each other, the small chunks that break off are called meteoroids
Meteor: If a meteoroid enters the Earth’s atmosphere, it begins to vapourise and then becomes a meteor. On Earth, it’ll look like a streak of light in the sky, because the rock is burning up
Meteorite: If a meteoroid doesn’t vapourise completely and survives the trip through Earth’s atmosphere, it can land on the Earth. At that point, it becomes a meteorite
Comet: Like asteroids, a comet orbits the Sun. However rather than being made mostly of rock, a comet contains lots of ice and gas, which can result in amazing tails forming behind them (thanks to the ice and dust vaporizing)
