 Nasa asteroid warning 2021: Eiffel Tower-sized asteroid heading towards earth in December - should we worry?

With the deadly plague of coronavirus on the horizon for two years, the last thing mankind needs is a Armageddon situation where a monster asteroid threatens to crash into the earth.

And yet such an event is on the cards, after Nasa unveiled a spacecraft larger than the Eiffel Tower of Paris and The Shard of London will pass through our home world.

The “potentially dangerous” asteroid 4660 Nereus is set to ‘shut down’ and die this weekend - just two weeks before Christmas Day 2021.

It follows the heat on the heels of another asteroid that was about the size of London Eye called the 1994 WR12, which crashed into the beard of our planet in November.

Work on how to stop crashing into the earth's crust is still growing, as the US space agency recently launched the first human effort to change the course of the celestial star.

So humanity should be concerned about 4660 Nereus, how did Nasa know it could kill - and what did the space agency do to prevent Armageddon?

Here's what you need to know.

Will the 4660 Nereus come to earth?

On Saturday (December 11), the 330m Nerous Navyus 330m long will fly at 6.58 km per second (14,719mph) - though 2.4 million miles away from our planet.

While that may not seem very close - after all you have to drive around the earth 100 times to travel that far - Nasa has classified the asteroid as a "potentially dangerous" object near the Earth.

This is because it is larger than 150m and will be closer to our planet less than half the distance from the earth to the sun (approximately 93 million miles), which means that any slight deviation from its orbit would put it at risk of crashing into Earth.

And it is closer to Earth than the 1994 WR12, which was 3.8 million miles away when it came very close on November 29th.

The gemstone is believed to contain elements such as nickel, iron, and cobalt - precious metals worth about $ 5 billion.

While the 4660 Nereus may not be a threat this year, it will be very close to the world in the future.

On Valentine's Day in 2060, it will reach between 745,000 miles around the earth - almost twice the distance between the earth and the moon.

Therefore you may need to buy those flowers or have that proposal made before that date, in the event that its circulation deviates.

How does Nasa track 'dangerous' asteroids?

Nasa tracks dangerous asteroids through the Center for Near-Earth Object Studies.

Since 1968, it has tracked more than 1,000 asteroids that have passed along our home planet using radar - a process that allows the space agency to accurately map the orbit, size, and orientation of the celestial rocks.

With binoculars, NASA has also been able to identify 27,323 asteroids that could pose a threat to the earth.

Just under 10,000 of these are 140m or more and 891 are over a mile in size.

To highlight the potential impact of these rocks when they hit the ground, the asteroid that caused the Chelyabinsk explosion in Russia in 2013 was just 20m in size.

When it exploded in space, the space shuttle released 33 times more energy than the US atomic bomb dropped on the Japanese city of Hiroshima during World War II.

Shocking from the blast shattered windows in more than 3,600 apartments and injured 1,200 people.

Some develop skin rashes and retina burns as a result of the sky being 30 times brighter than the sun as it burns in the earth's atmosphere.

Nasa says there is “no big chance” any of the closest asteroids it has seen will hit the earth in the next 100 years.

But it does estimate that it sees only half of the dangerous rocks in the atmosphere, as there are some 25,000 large objects near the earth's atmosphere.

By tracking them and finding out more about their size, shape, size, shape and composition, the American space agency hopes to come up with ways to divert humanity from invading the earth.
