CNEOS closely monitors all known near-Earth objects that could come within 1.3 astronomical units which translates to 1.3 times the distance between Earth and the Sun.
So far, 8,000 near-Earth asteroids with a diameter greater than 460 feet are being tracked. And a space rock this large could destroy an entire state if it has a direct hit on the U.S.
None of these objects are currently posing a direct threat to the Earth for decades. But a dangerous near-Earth object will potentially take decades to prepare for.
Live coverage will be streamed on NASA TV. And can also be seen on the NASA app, and on its website.
