The asteroid, called NASA Asteroid 2019 BC3, tomorrow will make the so-called "rapprochement of the Earth." On Thursday, January 31, NASA's asteroid trackers narrowed the asteroid pass to 5.59 pm GMT. When this happens, the asteroid BC3 will sway the Earth at an incredible speed in excess of 29,500 miles per hour or 13.22 kilometers per second. Fortunately, there is nothing to worry about, as the asteroid still sees the Earth almost three million miles (4.67 million km) when the brush approaches.
But the size and speed of the asteroid is a force to be reckoned with – enough for NASA to pay close attention.
According to the US space agency, an asteroid is what astronomers call the "near-Earth object" (NEO).
All NEOs are asteroids and comets on orbital trajectories that dangerously bring them closer to our home world.
NASA explained: “When they revolve around the sun, near-earth objects can sometimes approach the Earth.

"Please note that the astronomically" close "passage can be very far in human terms: millions or even tens of millions of kilometers."
Near-Earth objects can sometimes come close to the ground.
Scientists at NASA's Jet Propulsion Laboratory in Pasadena, California, believe that the asteroid BC3 is about eight times longer than the London double-decker bus.
The asteroid has dimensions ranging from 101.7 to 226.4 feet (31 to 69 m) in diameter.
At the top of this scale, an impressive space stone is 30 times longer than a queen-size bed and 17 times longer than a Volkswagen Beetle.

Even if the asteroid is closer to 101.7 feet wide (31 m), BC3 can still be an absolutely catastrophic threat if it hits the Earth.
A much smaller asteroid wounded 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 quietly entered the Earth’s atmosphere and exploded over Russia at high speeds.
The resulting arblast broke over the Chelyabinsk region with 30 times the power of the Hiroshima nuclear bomb.

After an attack on an asteroid, NASA called the cosmic rock "a space alarm signal to the dangers lurking in space."
Lindley Johnson, a planetary defense officer at NASA, said: "The Chelyabinsk event attracted widespread attention to what else needs to be done to discover even larger asteroids before they hit our planet."
But the good news is that Asteroid BC3 will not hit the Earth tomorrow afternoon, even with a close approximation.
JPL scientists from JPL believe that space rock will approach Earth with an estimated 0.03122 astronomical units (au).

One astronomical unit is the distance from Earth to the Sun, which is about 93 million miles (149.6 million km).
The asteroid BC3 will significantly reduce this distance tomorrow to 2.9 million miles (4.76 million km).
This is roughly equivalent to 12.15 lunar distances (LD) or 12.15 times the distance from Earth to the Moon.
After BC3 flies past Earth, NASA's asteroid trackers do not expect the space rock to visit our corner of space again in the future.
