The asteroid, known as NASA's Asteroid 2019 BC3, tomorrow will be the so-called "Earth approach". NASA's asteroid trackers on Thursday, January 31, have reduced the asteroid transition to at. Fortunately, there is nothing to worry about, as a close brush will still see an asteroid missed by the Earth for almost three million miles (4.67 million miles).
However, the huge size and speed of the asteroid is a force to take into account – enough for NASA to pay special attention.
According to the US Space Agency, an asteroid is what astronomers call a “dipped earth object” (NEO).
NEOs are asteroids and comets on the orbital trajectory that brings them dangerously closer to our home world.
NASA explained: “Because the nearby Earth objects in orbit around the Sun, they can sometimes approach Earth.

Objects close to the Earth can sometimes approach the Earth
"Note that a" close "astronomical path can be very far from a human: millions or even tens of millions of kilometers."
NASA Jet Propulsion Laboratory (JPL) scientists at Pasaden, California, estimate that the Asteroid BC3 is about eight times longer than the London Duplex Bus.
The asteroid is measured somewhere in the range of 101.7ft to 226.4ft (31m to 69m) in diameter.
At the top of this scale, the impressive space cliff is 30 times longer than the queen size bed and 17 times longer than the Volkswagen Beetle.

Even if the asteroid turns out to be closer to 101.7 feet (31 m), the BC3 could still be an absolutely catastrophic threat to the Earth.
A much smaller asteroid injured more than 1,500 people and damaged more than 7,000 buildings when it hit the planet six years ago.
The so-called Chelyabinsk meteor of 2013 came to the Earth's atmosphere undetected and at high speed, where it exploded over Russia.
The resulting tea rose above the Chelyabinsk region with the force of 30 times Hiroshima nuclear power.

After the asteroid attack, NASA called the space fence a "cosmic call to dangerous sites."
NASA Planet Defense Officer Lindley Johnson said: “The Chelyabinsk event brought a lot of attention to what needs to be done to discover even more asteroids before they enter our planet.
But the good news is the asteroid BC3, which will not touch the Earth tomorrow afternoon even in the nearest approach.
NASA JPL scientists believe that the space rock will approach the Earth from about 0.03122 astronomical units (au).

NASA Asteroid Warning: The asteroid BC3 is eight times longer than the London bus
One astronomical unit is the distance from Earth to the Sun and is about 93 million miles (149.6 million km).
The asteroid BC3 will significantly reduce this distance to just 2.9 million miles (4.76 million km) tomorrow.
It is approximately equivalent to 12.15 Lunar Distances (LD) or 12.15 times the distance from Earth to Moon.
After BC3 swaying under Earth, NASA asteroids will not expect space space to visit our space corners again in the future.
