Small asteroid to closely pass Earth on Thursday, says NASA
New Delhi: American space agency NASA has reported that a small asteroid will safely whizz past Earth on Thursday at a distance of approximately 42,000 kilometres. This is just above the orbital altitude of communication satellites.
The fly-by of the asteroid designated 2012 TC4 will give asteroid trackers around the world an opportunity to test their ability to operate as a coordinated international asteroid warning network.
On 1st September, Florence- a giant asteroid- has also made an appearance close to Earth.
When it zoomed past within a mere 4.4 million miles (7 million kms) of Earth.
“Asteroid trackers are using this flyby to test the worldwide asteroid detection and tracking network, assessing our capability to work together in response to finding a potential real asteroid-impact threat,” said Michael Kelley, Program scientist and NASA Planetary Defence Coordination Office(PDCO) lead for the TC4 observation campaign.
The asteroid is estimated to be 15 to 30 meters in size, and according to orbit prediction experts, it poses no risk of impact with Earth.
This asteroid was discovered by the range of asteroid-tracking telescopes shortly after it was discovered.
On the observations they could make in 2012, asteroid trackers predicted that it should come back into view in 2017.
Observers with the European Space Agency and the European Southern Observatory were the first to recapture 2012 TC4, in late July,2017, using one of their large 8-meter aperture telescope.
Observers around the world have been tracking the object as it approaches Earth and reporting their observations to the Minor Planet Centre.
No asteroid currently known is predicted to impact Earth for the next 100 years, NASA said.
