“Experts are unsure about where and when it will land.
“The object is a 21-ton leftover from China’s Long March 5 rocket, which carried a piece of its new TN space station into last month.
“Reports are suggesting this space junk is out of control and heading for Earth, should we be worried Brad Tucker?”
Mr Tucker explained the difficulty of predicting where the space debris would land and when.
He also discussed the responsibility of China for the rocket once it lands.
He said: “Uncontrollable and heading for Earth are obviously not words you want to peace together.
“This is the reality of the situation. Once you lose control of a piece of debris that is pretty much it, you can’t really solve it.
He said: “There is a famous case in 1979 when Skylab, the US space station, crashed in Esperance in Western Australia.
“That was really the first big piece of space junk that weighed about 70-71 tons.
“It was a lot bigger, it didn’t hit anyone but it did land near a populated area.
“Ultimately it was actually Australia who had to deal with it.
“Even if the Chinese debris does land in a populated area or country, the country that it lands in will have to deal with it.”
