The asteroid that will fly past the earth, will help scientists

Kristine Garrett | 14 October, 2017, 08:27

That's about one-tenth of the distance to the moon, and just beyond the orbit of Earth's satellites.

NASA representative Paul Cadas told BBC News: "With the help of this asteroid we're going to test a system that will monitor the asteroids, to describe them and to consider how close they fly, in case if one day will arrive a guest, what can we get".

Rudiger Jehn, a mission analyst at the European Space Agency, said, "We know today that it will also not hit the Earth in the year 2050, but the close flyby in 2050 might deflect the asteroid such that it could hit the Earth in the year 2079".

Scientists have said the asteroid is on course to pass safely by, just south of Australia, and poses no threat.

Following yesterday's pass, the asteroid's next "close-approaches" to Earth will take place in 2019, 2050 and 2079. All the more reason to point more eyes and lenses toward the sky to find the 99 percent of asteroids in the solar system big enough to level a city that are believed to still be undiscovered. However, 2012 TC4 travelled out of the range of asteroid-tracking telescopes shortly after it was discovered. As of right now, no known asteroid is projected to hit Earth in the next 100 years.

There is absolutely no risk TC4 will hit Earth.

In 2013, a meteor of similar size entered the atmosphere over the Russian town of Chelyabinsk.

But according to tracking models, the asteroid's path will be altered by Earth's gravity in the future, and after a few more flybys, its trajectory could lead straight into Earth.

The detection program involves "more than a dozen observatories, universities and labs around the globe" in what campaign leader Vishnu Reddy with the Lunar and Planet Laboratory at the University of Arizona called a "team effort", Space.com reported.

"This effort will exercise the entire system, to include the initial and follow-up observations, precise orbit determination, and worldwide communications".
