The Aitken basin, on the south pole of the Moon, may contain a very dense object, as revealed in new information coming out of NASA. It is believed that the unusual sector may be the influence of a heavy metal asteroid impact that occurred millions of years ago.
The efforts of the NASA Gravity Recovery and Interior Laboratory (GRAIL) and Lunar Reconnaissance Orbiter marked a topography failure and began investigating the Moon's mass anomaly.
Peter B. James, a geoscientist at Baylor University in Texas and lead author of the study, said: "Imagine taking a metal stack five times larger than Big Island of Hawaii and bury it in the basement. That's roughly the amount of unexpected mass we detect. "
The Moon's gravitational pull was mapped at NASA's GRAIL mission, where two spacecraft used each other to signal for more than a year.
The mass anomaly of the moon at its south pole suggests an ancient impact of metal asteroid
The dark side of the moon, the Aitken basin, the anomaly's reserved space, features a huge crater, measuring 2000 kilometers (1,240 miles) in diameter. Being the largest, in fact, it is believed to have been formed 4 million years ago.
"One of the explanations for this extra mass is that the asteroid metal that formed this crater is still embedded in the moon's mantle," adds Peter B. James.
Another theory that explains the existence of the mass anomaly of the Moon was postulated by scientists. He claims that, due to the richness of oxides, the area was formed during the tumultuous past of the Moon, when vast masses of magma drained and solidified.
The Moon's anomaly in relation to the satellite's south pole, reaching 300 kilometers, is causing scientists to believe that the interior of the Moon must be solid so as not to force the heavy mass itself into gravitational forces.
