The asteroid, called by NASA Asteroid 2019 AX2, was first observed by radars on January 3 this year. NASA's astronomers now believe that the scruffy spacecraft is on its way to the ground with a dense flying city this afternoon. Saturday, January 12, the asteroid will make a so-called "Earth Close Approach" and fly past theEarth. NASA researchers at the California Jet Propulsion Laboratory (JPL) expect Asteroid AX2 to arrive at. 22.00 GMT (UTC).
Under its close approach, the asteroid is expected to miss the planet by more than four million miles (6.7 million km).
But the asteroid is understood to be higher than the crooked tower of Pisa and Nelson's Column in London, which is a good enough reason for NASA to track space rocks.
NASA's JPL researchers estimate Asteroid AX2 measures somewhere between 1
An asteroid this great is more than three and a half times as long as a bowling alley and 8.4 times longer than a London double
Even at the lower end of the estimate, the asteroid stands five times higher than an average giraffe .

Much smaller asteroids have been known to cause unimaginable damage when hitting the planet.
As an estimated volume of 65.6 meters in width spread into Earth's atmosphere at high speeds in 2013 over Russia's Chelyabinsk oblast, more than 1,500 people were injured.
The chelyabinsk meteor eruption in the middle of the air with a powerful air blast that bursts windows across the region.
After the unlikely asteroid attack, the NASA called the Chelyabinsk meteor a "cosmic wake call" to the dangers that lurk in space.

NASA's planetary defense officer Lindley Johnson said: "The Chelyabinsk event exclaimed great attention to what needs to be done to discover even larger asteroids before they hit our planet. "Fortunately, Asteroid AX2 will not come close enough to hit the ground with devastating power.
In the near future, the so-called "Near Earth Asteroid" (NEA) will approach within 0.04 508 astronomical units (au) of the earth.
Astronomers define an astronomical unit as the distance from the Sun to Earth, and this measures approx. 93 million miles (149.6 million km).

NASA expects Asteroid's AX2 to trim this impressive distance down to only 4.19 million miles ( 6.774 million km).
This is equivalent to 17.55 times the distance from ground to moon – 17.55 Lunar Distances (LD).
According to NASA, all asteroids and comets that come within 30 million miles of Earth's orbit around the Sun are near Earth objects. "
As the barrels around the sun, NEO & # 39; comes into the solar system within 121 million miles (195 million miles) of the Sun.
NASA said," When they orbit the sun, Near Earth objects may occasionally approach Earth.
Please note that a & # 39; close & # 39; passage astronomically can be very far away in human terms: millions or even tens of thousands of kilometers. "
After Asteroid AX2 passes Earth, NASA expects the space rock to visit the Earth's corner of the room at least three times.
Next flight city is scheduled to take place in the morning of January 5, 2033, followed by 26 August 2085 and September 2, 2134.
