They say there's no risk of it hitting Earth, but at the same time, scientists say they're not sure exactly how close that near-Earth asteroid 2013 TX68 will get when it passes by on March 8th.
Estimates range anywhere from 3 million miles to just 15,000 miles, which puts it closer than many satellites.
