For comparison, some of the other asteroids on the Risk List measure 900 and 375 meters in diameter.
This fall, Earth has about a 1-in-7,000 chance of getting an uninvited extraterrestrial visitor: asteroid 2006 QV89. It is now around 4.2 million miles away from the Earth, and, despite there being a chance the modeling might be off, the ESA noted that the chance is less than one-hundredth of 1 percent. While, many other news reports talked about this event as a risky one, accentuating the significance of the flyby of the 2006QV89 massive asteroid, in reality, this space rock is a Near-Earth Object (NEO), some types of asteroids located near our planet but which are strictly tracked down by space agencies. However, it was not the first time that the space rock flew close to Earth.
NASA's trackers at the Jet Propulsion Laboratory (JPL) estimates the space rock will make its closest approach to our planet at 9.40pm BST or 4.40pm Eastern Time.
According to NASA, the number of discovered near-Earth asteroids totaled more than 19,000 at the start of 2019. NASA has predicted that the asteroid will come alarmingly close to Earth on a so-called Earth Close Approach trajectory.
The asteroid, named 2002 AJ129, was estimated by NASA to be 0.68 miles in diameter-more than the height of the world's largest building, the Burj Khalifa, and the width of Central Park, both of which are about half a mile. 2019 KZ3 will have a speed of about 22,000 miles per hour as it flies past Earth.
The present shape of the cosmic object's orbit discloses that it is probably passing by Earth at a distance of more than 4.2 million miles (6.8 million kilometers) this September, but ESA states that there is a tiny one hundredth of one percent chance the model is further away and it will collide into the Earth instead. The flash of light caught the attention of amateur astronomers as the moon was eclipsed by the Earth and shrouded in darkness. However, scientists say we should not worry as it nearly definitely won't impact Earth.
