NASA's CNEOS department has tracked the asteroid since 2015. It is due to make a close approach this week.
The U.S. space agency has been running an imaginary scenario in which Earth is due to be hit by a hypothetical space rock.
The pretend impact scenario sees an asteroid heading towards central Europe, and will aim to see "who the key players are in a disaster event."
NASA announced this week it will conduct a hypothetical asteroid impact scenario to see how international organizations react.
Asteroid 2021 GW4, which flew past Earth last night, was first spotted by astronomers on April 4, according to NASA.
The spacecraft will investigate a metallic asteroid and scientists hope this could give an insight into how the Earth was formed.
Astronomers had calculated that there was a small chance that the space rock could collide with our planet in 2068.
At the time of close approach, 2001 FO32 will be travelling at nearly 77,000 miles per hour.
The space rock called 2021 EQ3 will not hit Earth, but it will be close enough to be tracked by telescopes.
The rock, which is traveling at nearly 77,000 miles per hour, is due to come closest to Earth on March 21.
2001 FO32 is likely the largest asteroid to make a close approach to Earth in 2021.
The hulking space rock will come relatively close, but should zoom past at around 77,000 miles per hour.
The space agency said it had received over 100 eyewitness reports and also detected the sound made by the fireball.
The asteroid is estimated to measure more than 1,100 feet in diameter.
The large space rock will zoom past our planet at a distance dozens of times further away than the moon—but a much closer approach is due in 2029.
Scientists think the asteroid is at least as big as the Eiffel Tower, and it's travelling at over 10,000 miles per hour.
Apophis is deemed potentially hazardous because of its size and occasional proximity to our planet.
Apophis has captured the attention of scientists for years due to the tiny chance it will collide with the Earth in decades' time.
This is the best chance for scientists to get a good look at the space rock Apophis before it makes an extremely close approach to our planet in 2029.
At the time of close approach, the asteroid will be travelling at around 30,000 miles per hour.
The giant space rock will make a close approach to our planet on March 21. About 25,000 near-Earth objects have been identified so far, according to NASA.
Based on its brightness, astronomers estimate that the asteroid measures between around 2,500 feet and 5,500 feet across.
During this flyby, the asteroid will be traveling at a staggering speed of roughly 40,400 miles per hour, which is around 20 times faster than a rifle bullet.
The space rocks will make their close approaches on January 23 and 25.
The space rock, estimated to measure up to 1,345 feet in diameter, is set to pass Earth on January 17.
The space rock will be traveling at approximately 33,700 miles per hour as it flies past our planet.
The best time to view the Quadrantids for observers in North America will be during the predawn hours of Sunday morning.
The space rock will be travelling at a speed of more than 22,000 miles per hour.
The object, which is estimated to measure between 15-33 feet across, was discovered on September 17, 2020.
