Asteroid to pass Earth; how near remains unclear

TUCSON, AZ (Tucson News Now) -

A small asteroid is expected to pass by Earth on March 5.  However, the exact track of the asteroid isn't clear. Scientists at NASA say it won't impact Earth, but it could pass anywhere between 9 million and 11,000 miles from us.

Asteroid 2013 TX68 was discovered right here in southern Arizona, as part of the Catalina Sky Survey on Oct. 6, 2013.  It could only be tracked for a short time, which is why there is still so much uncertainty on the asteroid's exact orbit around the sun.  

The asteroid is about 100 feet wide. The asteroid that hit Chelyabinsk, Russia in 2013 was 65 feet wide.

While there is no possibility of this asteroid hitting Earth next month, NASA scientist have identified a very small possibility of a collision on Sept. 28, 2017. The odds of this happening are 1 in 250 million.
