In a post on the space agency’s website, scientists explained: “Surprisingly the crater is actually two craters, an eastern crater (18-meter diameter, about 19.5 yards) superimposed on a western crater (16-meter diameter, about 17.5 yards).
“The double crater was unexpected and may indicate that the body had large masses at each end.
“Typically a spent rocket has mass concentrated at the motor end; the rest of the rocket stage mainly consists of an empty fuel tank.
“Since the origin of the rocket body remains uncertain, the double nature of the crater may indicate its identity.”
Astronomer and data scientist Bill Gray told the BBC he believes the rocket belongs to China, after initially thinking it may have come from a rocket launched by Elon Musk’s Space X.
After running new data received by an amateur observer, Gray believes the rocket came from is the third stage of Chang'e 5-T, a Chinese rocket lunar mission launched in October 2014.
Gray said: “I'm 99.9 per cent sure it's the China 5-T1.”
China has denied this, claiming that that stage of its rocket has already re-entered the Earth's atmosphere and burned up.
