A six-ton NASA satellite penetrated Earth's atmosphere early Saturday morning and landed somewhere in the Pacific Ocean.
It is the largest satellite to fall back to Earth uncontrolled in more than 30 years, the Star Tribune reported.
The satellite partially burnt up during its re-entry and broke up into hundreds of pieces, the largest of which is estimated to be around 300 pounds.
NASA predicted that the debris spread over a 500-mile swath, the Los Angeles Times reported.
NASA estimated the chances of somebody getting hit and hurt from the falling satellite at 1-to-3,200.
