For an uncontrolled re-entry event like this, it is not possible to accurately predict where the object or parts of the object will fall, the European Space Agency (ESA) says.
This is mainly because atmospheric density, which is what will push the rocket’s altitude to eventual re-entry, is not known below 300 kilometres because spacecraft do not fly at such low heights.
The Long March 5B rocket is currently fluctuating at an altitude of between 170 and 372 kilometres, but has been seen dropping to 160 kilometres today.
It is also likely that the object will simply burn up on re-entry, but parts of the rocket with a high melting point could make it to the ground. Experts struggle to know exactly how the rocket will make it through its re-entry, because the Chinese space agency only gives limited information about its spacecraft.

The world is heading for a wild west free for all in space that could lead to disaster as firms fight for every scrap of resource in low Earth orbit, an expert has warned.
Paul Kostek, a space policy specialist from the Institute of Electrical and Electronics Engineers (IEEE), says global agreement is highly unlikely anytime soon.
As the commercial space sector continues to grow at a rapid rate, firms are vying to launch constellations of satellites and new experimental craft into low Earth orbit.
This has left astronomers frustrated and struggling due to blots in the sky that make observations harder and less accurate, as well as concerns over space junk.
