SUV-shaped asteroid flies in the closest known flyby to Earth

NEW DELHI: A car-shaped asteroid flew over our home planet over the weekend, into the flyby closest to such space rocks on record and scientists hardly had any idea about it until it sailed Not done.
NASA said on Tuesday that the asteroid passed 2,950 kilometers above the southern Indian Ocean at 12.08 am EDT (9.38 pm India time).
The vast majority of Near Earth Asteroids, or NEAs pass safely over much greater distances – usually far away from the Moon.
The first image of this record-setting space rock, the asteroid 2020 QG, was taken about six hours after the nearest point by a NASA-funded facility as the asteroid was moving away from Earth.
NASA said that at a distance of about three to six meters, the asteroid is much smaller than the 2020 QG asteroid standards.
According to some estimates, there are millions of small asteroids the size of 2020 QG, but until they reach very close to Earth, they are extremely difficult to discover.
Paul Chodas, director of the Center for Near-Earth Object Studies (CNEOS) at NASA’s Jet Propulsion Laboratory, said, “It is great to see a small asteroid up close, as we see Earth’s gravity dramatically change its trajectory.” Can be seen turning. ” Southern California.
“Our calculations show that this asteroid has changed by 45 degrees or so because it has been struck by our planet.”
Running at a speed of approximately 12.3 kilometers per second by 2020, the QG is first shown as a long streak in a wide-field camera image taken by the Zwicky Transient facility, a sky-scanning survey telescope funded by the US National Science Foundation and NASA, Chodas. Was recorded as. .
The facility is located at the California Institute of Technology’s Palomar Observatory in San Diego County.
While the asteroid 2020 QG recorded it as the most known non-impacted asteroid in the record book, many very small asteroids impact our planet every year and in fact only a few space hours before Earth was impacted Have been found in
On average, an asteroid the size of 2020 QG passes it only a few times a year, NASA said.
If the asteroid 2020 QG was indeed on an impact trajectory, it would likely become a fireball as it broke into Earth’s atmosphere.
