NEW DELHI: A car-sized asteroid flew past our home planet over the weekend, in the closest flyby of such space rocks on record and scientists hardly had any information about it until it departed.
The asteroid passed 2,950 kilometres above the southern Indian Ocean on Sunday at 12.08 am EDT (9.38 pm India time), NASA said on Tuesday.
The vast majority of Near Earth Asteroids, or NEAs pass by safely at much greater distances — usually much farther away than the Moon.
The first image of this record-setting space rock, asteroid 2020 QG, was taken by a NASA-funded facility six hours after the closest point of approach as the asteroid was heading away from Earth.
NASA said at roughly three to six metres across, asteroid 2020 QG is very small by asteroid standards.
By some estimates, there are hundreds of millions of small asteroids the size of 2020 QG, but they are extremely hard to discover until they get very close to Earth.
"It's really cool to see a small asteroid come by this close, because we can see the Earth's gravity dramatically bend its trajectory," said Paul Chodas, Director of the Center for Near-Earth Object Studies (CNEOS) at NASA's Jet Propulsion Laboratory in Southern California.
"Our calculations show that this asteroid got turned by 45 degrees or so as it swung by our planet." (IANS)
