Residents of planet Earth fret not -- a 1,000-foot asteroid whizzing by our precious planet this weekend won't even come close to making impact.
About 25 asteroids are expected to fly within 5 million miles of the earth in the next 60 days, and smaller asteroids pass even closer"all the time," Johnson said.A larger object, asteroid 2000 QW7 is expected to pass even closer to the earth -- at about 3.5 million miles away -- on Sept. 14. The largest that asteroid could be is about 1,700 feet across -- about the length of five football fields -- but Johnson said he still considers it"not that large.
In addition, it's difficult for astronomers to model an exact track due to forces like solar wind, aviation pressure and the uncertainty of the exact shape of the object," Pete Worden, adviser on space resources to the Grand Duchy of Luxembourg, told ABC News. Once the asteroid gets closer, the better scientists can track it, he added.
Scientists are currently devising ways to detract any asteroid that could potentially impact the earth.
