Asteroid close approach to test warning systems

RATE THIS! +31
Posted in Science on 11th Oct, 2017 07:44 PM by Alex Muller

The space rock will hurtle past our planet at a distance of about 42,000km (26,000 miles), bringing it within the Moon's orbit and just above the altitude of communication satellites. Nasa scientists say there is no risk of an impact, but the flyby does provide them with the opportunity to test their asteroid-warning systems.

 

A global network of telescopes will be closely monitoring the object. Paul Chodas, manager of Nasa's Centre for Near Earth Object Studies (CNEOS) at the Jet Propulsion Laboratory in California, told BBC News:
 
"We are going to use this asteroid to practise the system that would observe an asteroid, characterise it and compute how close it is going to come, in case some day we have one that is on the way inbound and might hit."
 
The asteroid, called 2012 TC4, was first spotted five years ago. It is estimated to be between 15m and 30m (50-100ft) in size, which is relatively small. However, even space rocks on this scale are dangerous if they strike.
 
When a 20m-wide asteroid exploded over Chelyabinsk in central Russia in 2013, it hit the atmosphere with energy estimated to be equivalent to 500,000 tonnes of TNT, causing a shockwave that damaged buildings and injured more than a thousand people.
 
Nasa scientists who have spent the last two months tracking this new rocky visitor say their calculations show that it will safely clear the Earth and poses no threat.
 
Instead, they will use this close approach to rehearse for future potential strikes.
 
More than a dozen observatories, universities and labs around the world will be watching 2012 TC4 as it flies past.
 
This will help them to refine how asteroids are tracked and provide a chance to test international communication systems.
 
Dr Chodas said that while the risk of an asteroid hit was small, it was prudent to plan ahead.
 
"Nasa search programmes are getting better and better at finding asteroids," he explained.
 
"It's been a priority to find the large asteroids first. So far the Nasa surveys have found 95% of the asteroids that are one kilometre and larger - these are the ones that could cause a global catastrophe.
 
"Now we are working our way down to the smaller ones - 130m in size and larger - and we are around 30% on that.
