2019 OD, one of the asteroids which was travelling at a speed of 42,926mph crossed the Earth’s orbits within 222,164 miles from the surface, this made it 16,736 miles closer than the Moon. The asteroid was 393 feet across in width at its widest point. In addition, 2019 OE came within 600,494 miles at 2.36pm GMT whilst 2015 HM10 reached 2.9 million miles from Earth at 6.00am GMT.
NASA said none of these asteroids posed a threat to Earth.
However, the two other asteroids also travelled at breakneck speeds.
The 361ft wide 2015 HM10 was clocking at 21,273mph while 2019 OE which was a smaller 170ft across reached 20,244mph.
2019 OD could have travelled from London to Australia about four times in one hour at that speed.
The other two could have reached the Venezuelan capital Caracas as many times in around one hour at their respective speeds.
CNN reported that in June, astronomers showed that advancement in telescopes could be able to warn people about an impending asteroid strike on our planet and given ample time for evacuation from affected areas.
A team at the University of Hawaii were able to detect 2019 MO, which was just 13 feet in diameter before it entered the Earth’s atmosphere.
The space rock got within 310,685 miles from Earth.
Davide Farnocchia, who works as a scientist for NASA’s Centre for Near Earth Objects told Metro.co.uk at the time: “Asteroids this size are far smaller than what we’re tasked to track.
“They’re so small, they would not survive passing through our atmosphere to cause damage to Earth’s surface. But this event shows how capable our search programs are, even for objects of such small sizes.”
The asteroid broke up in the atmosphere but if it was larger, it could have the potential to cause serious damage.
NASA had earlier this year confirmed it will build the Double Asteroid Redirection Test (DART) which will in 2022 be tested to see if it can hit a small moonlet in the asteroid system Didymos, which could help scientists develop systems that could deflect away dangerous asteroids.
