The deadly asteroid, larger than a half-house, was nominated by NASA as an Asteroid 2018 WN. The huge space rock is expected to have the Earth's closest look that its closest look to our planet as it goes ahead at 11.49am GMT. Although NASA's astronomers have calculated that the asteroid is not a trajectory to sneak into our world, its destructive potential is still inspiring.
NASA Jet Propulsion Laboratory scientists estimates the asteroid measures ie in the region 40ft to 91ft (12m to 28m).
Asteroid 2018 WN may not spell the end of life on the ground, as we know, but even the lowest end of the NASA's rating of witches can potentially be a danger to very populated areas.
More than 1,000 people were injured in 2013 after a 65th wide space rock erupted over the Russian city of Chelyabinsk.
The resulting effect scratched windows, sending glass glasses into the victims' bodies.

According to Dr. Matija Cuk, Cornell University in New York City, impacts with these smaller asteroids are rare and there are no known cases of fatigue.
The space expert said: "With regard to smaller meteorites that hit the ground, they are very low in danger and no one has ever been reported killed by a small meteorite.
"I heard a story that a dog was killed by a meteorite, which fell in 1911 in Nakhla, Egypt, and there were also examples of material damages.
"However, traffic, pollution and even lightning are much more dangerous than small meteorites."

Astronomers have recently accepted the presence of unknown asteroids in our galaxy – some of which require a threat to live on Earth.
Researchers at the University of Madrid have tried to calculate the likelihood that large asteroids are fragmented into smaller pieces that will destroy our planet.
The products of "catastrophic" collisions are almost impossible to track for their "chaotic pre-effective orbits".
And if an enormous asteroid made a trajectory with Earth, it would not allow time to evacuate those in the shooting.

The researchers wrote: "Asteroids can deliver meteorites to the inner planets when their paths intersect the planets at time, causing effect".
"On Earth, the meteorites collected after the observance of shining fireballs were sometimes tempted to the near object of the Earth or collision events in the main asteroid."
The scientists discussed a last impact by an object called 2018 LA, between nine and 12 ft wide, which hit the Earth only hours after detection.
The asteroid hit the Earth's atmosphere at 38,000 mph, causing a terrible firebone to cross the sky over Botswana.
"This was a much smaller object than we were tasked to detect and warn," said Lindley Johnson, NASA Planetary Defense Officer.
In his new paper, the two Spanish researchers warned that only "three natural objects were discovered before colliding with Earth."
It is possible that 2018 was formed during a massive collision between two or more rocks in the asteroid zone – meaning more meteors on the way.
The researchers discovered "more than two dozen" asteroids, which "resemble" 2018 according to their size, shape and direction in space.
