The asteroid, dubbed by NASA Asteroid 2019 AR2, will make a so-called "Approach close to Earth". The asteroid trajectory calculations predict that the space rock will reach its closest distance to the Earth tomorrow afternoon. NASA's Jet Propulsion Laboratory (JPL) predicts that Asteroid AR2 will swing around 2.28 on Sunday, January 13th. The unexpected flyby arrives only 10 days after the bombing rock was detected for the first time by NASA's radar on January 3rd.
And during the flyby tomorrow, it is estimated that the asteroid crashes over the Earth at a dizzying speed of over 10,780 miles per hour (4.82 km per second).
Luckily, NASA does not expect space rock to crash into the Earth at any time.
the asteroid will skip the Earth by nearly two million miles.
But the asteroid is big enough and will swing close enough for NASA to pay close attention to its journey around the solar system.

The JPL estimates that the AR2 asteroid measures somewhere in the range of 1
A large asteroid is about 10-ti is longer than a two-story red London bus and is 1.45 times taller than the Tower of Pisa.
Even at the lower end of the estimate, the asteroid is nine times longer than a Volkswagen Beatle car.  And the much smaller asteroids of AR2 have been known to cause chaos and destruction when they hit the Earth.

The most recent example is the Chelyabinsk Meteor of 2013 , which exploded over the Chelyabinsk region in Russia six years ago.
The 20-meter meteor was not detected until it entered the Earth's atmosphere and wounded more than 1, 5,000 people when windows exploded in a wide range.
NASA surnamed the terrifying incident a "cosmic alarm" for the dangers that lurk in deep space.
The US space agency said: "The explosion released more than 30 times the energy of the atomic bomb that destroyed Hirosh ima."
Tomorrow, the asteroid AR2 will miss the Land of about 0.01954 astronomical units (au) or 1.8 million miles (2.92 million km).
This is approximately the equivalent of 7.60 times the distance between the Earth and the Moon.
Because of the distances involved, NASA has defined the asteroid AR2 as an "object close to the earth".
The NEOs are described as any asteroid or comet that pass the Sun within 1.3 astronomical units or 120.8 million miles (194.4 million km).
NASA said: "Objects close to the Earth (NEO) are comets and asteroids that have been affected by the gravitational attraction of nearby planets in orbits that allow them to enter the neighborhood of the Earth."
