Of these, we are now aware of about 900 NEOs measuring more than 3,280 feet in diameter.
The asteroid is 164 meters in diameter and its size is nearly equivalent to the Washington monument.
Unlike the planet-killer asteroids, the destruction caused by an impact from a smaller one will be more localized. As it goes through its path around these cosmic bodies, it intersects with the orbit of Earth at certain points.
Despite the certainty of an asteroid impact, Remy believes that Earth is not in danger of getting hit by planet-killer space rocks or those that are more than a kilometer in length. It should be noted that even a slight change in the trajectory of this asteroid could turn out to be very risky.
Kelly Fast, who runs the agency's Near Earth Object Observation program, commented: "The whole point is to be able to find all of these asteroids and to catalog their orbits precisely and to calculate them into the future".
"Potentially hazardous asteroids are now defined based on parameters that measure the asteroid's potential to make threatening close approaches to the Earth", CNEOS said in a statement.
454094 2013 BZ45 was first observed on January 19, 2013. To illustrate the distance, the Moon is about 0.38 million kilometers from Earth. According to CNEOS, the last time the asteroid approached Earth was on July 29, 2018.
After its visit this week, the asteroid is expected to return to Earth's neighborhood on August 27, 2021.
The space rock will come 10 times closer to Earth than Venus, our nearest neighbor, when it passes by at a distance of 0.049 astronomical units (4.6 million miles) while traveling at speeds of around 10,400 mph.
