The asteroid, named by NASA's Asteroid 2019 AG7, will make a so-called "Earth Close Approach" tomorrow. The space rock was first discovered on December 31, 2018 on New Year's Eve by space radars. The last known observations on Saturday, January 12, indicate that the asteroid is now heading for the planet. According to NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, the asteroid will fly past 22:43 GMT (UTC) on Tuesday, January 12.
During the flyby, the asteroid swings past our home planet the closest distance to Earth.
Fortunately, the asteroid will barely miss the planet by less than one million miles (1.5 million km).
But the close meshing of the asteroid with the earth and its imposing size is good enough to attract astronomers' attention.
NASA's JPL estimates that asteroid AG7 measurements range anywhere from 75.4 feet to 1

Such a large asteroid is almost like all the Arc de Triomphe in Paris and the Nelson Pillar in London.
Even at the bottom of the size estimate The asteroid is large enough to be considered a potential hazard
An asteroid of similar size injured more than 1,500 people in 2013 when it exploded over the Chelyabinsk region in Russia.
The so-called Chelyabinsk meteor exploded with 20 to 30 times higher power than an atomic bomb.

Asteroid experts believe the meteor is only about 65.6 feet wide (20 m).
A NASA report reads: Thousands of buildings and more than a thousand people were injured, mainly by broken glass by the shockwave .
"According to recent estimates, there are nearly 10 million NEOs larger than 20 meters, but they are extremely hard to spot before entering the Earth's atmosphere.
The good news is that asteroid AG7 will not have a chance tomorrow to cause similar damage when approaching Earth.

The asteroid will be in close proximity to our planet within 0.01008 astronomical units (AU) or 3.92 Lunar Reach Distance (LD).
An astronomical unit is the distance between the Earth and the Sun and measures 149.6 million kilometers.
Asteroid AG7 will reduce this distance tomorrow to approximately 1.5 million kilometers (936,994.54 miles).
This is about 3.92 times the distance from Earth to the Moon.
And on the night of the flyby, the asteroid will rush through space at a frantic pace of 15,188.8 miles per second or 6.79 km per second.
