The asteroid, called NASA Asteroid 2019 BC, will make the so-called "close approach on Earth" tomorrow. NASA's asteroid trackers have reduced the passage of asteroids by 5.59 am on Thursday, January 31. When this happens, the asteroid BK3 will turn to Earth at incredible speeds greater than 29,500 km / h or 13.22 kilometers per second. Luckily, there is nothing to worry about, because the nearby brush will still see the Earth's asteroid for nearly three million kilometers (4.67 million kilometers).
But the great size and speed of the asteroid is a force to be considered – enough for NASA to pay more attention.
According to the US space agency, the asteroid is what astronomers call "Near Earth Object" (NEO).
NEOs are all asteroids and comets of orbital trajectories that bring them dangerously close to our home world.
NASA explained: "While orbiting the Sun, objects near the Earth can occasionally approach the Earth.

"Keep in mind that the" nearby "passage astronomically can be very far in human terms: millions or even tens of millions of kilometers."

Scientists at the NASA Laboratory in Pasadena, California, estimate that the Asteroid BC3 is about eight times longer than a double bus in London.
Asteroid measures somewhere in the range 101.7 to 226.4mm (31m to 69m) in diameter.
At the upper end of that scale, the impressive space rock is 30 times longer than the queen size and 17 times longer than the Volkswagen Beetle.

Even if the asteroid is shown to be closer to a width of 101.7 meters (31 m), the BC3 can still be an absolutely catastrophic threat if it hit the Earth.
Many smaller asteroids injured more than 1,500 people and damaged more than 7,000 buildings when they hit the planet six years ago.
The so-called meteor Chelyabinsk 2013 entered the atmosphere of the Earth, undiscovered at high speeds, where it was going through Russia.
As a result of the distortion, it broke out over the Chelyabinsk area with 30 times more force than the nuclear bomb in Hiroshima.

After the attack on the asteroid, NASA called the space rock "a cosmic call to awaken the dangers that lurk in space."
NASA Planetary Defense official Lindley Johnson said: "The Chelyabinsk event drew a lot of attention to what needs to be done to detect even larger asteroids before attacking our planet."
But the good news is the asteroid BC3 will not hit the Earth tomorrow afternoon, even after its closest approach.
Scientists from NASA, JPL believe that the space rock will approach Earth from about 0.03122 astronomical units (au).

An astronomical unit is the distance from the Earth to the Sun and is about 149 million kilometers.
The asteroid BC3 will significantly reduce this distance tomorrow to just 2.9 million kilometers.
This is approximately the equivalent of 12.15 lunar distances (LD) or 12.15 times the distance from Earth to Moon.
Once the BC3 moves across the Earth, NASA's asteroid trackers do not expect the space rock to visit our corner of space again in the future.
