Astronomer Jonathan McDowell of the Harvard-Smithsonian Centre for Astrophysics said on Twitter: “It’s down! 0016 UTC.”
Tiangong-1 mostly burnt up upon reentry into the Earth’s atmosphere.
Mr McDowell added: “US tracking by 18SPCS confirms reentry over the S Pacific at 0016 UTC Apr 2.”
It has landed in the South Pacific after it re-entered the Earth’s atmosphere at around 2:16am GMT.
According to an estimate by The Aerospace Corporation, the Tiangong 1 space station’s fiery descent began at 12.30am UTC (1.30am GMT) on Monday.
It is believed that each year around 1,000 large objects fall back to Earth from space.
These numbers are projected to increase over the coming years as more and more satellites are placed into orbit.
America’s 77-ton Skylab crashed through the atmosphere in 1979, spreading pieces of wreckage near the southwestern Australia city of Perth, which fined the US $400 for littering.
