About the largest crater present on Moon the Lunar South Pole-Aitken


There are new researches every day that are making an astonishing entry to the diaries of all the new things that scientists are discovering on a daily basis. As per the new study, it was found that there are some signs of metal in the asteroid with hit our Moon a very long time ago which is known as the Lunar South Pole-Aitken basin. The reason behind calling it the Lunar South Pole-Aitken basin is because of the basin being situated in the south-pole of the lunar.

According to the lead author of the study Dr. Peter James, assistant professor of planetary geophysics at Baylor University, said in a┬ástatement, “Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That’s roughly how much-unexpected mass we detected.” The study was published in the journal Geophysical Research Letters in April 2019. The size of the moon and the basin was compared and it was found that the Aitken Basin covers one-fourth of the space on the Moon as it is around just 1,500 miles in the area compared to Moon which is 11,000 Kms roughly. According to the studies, it is clear that the Pole-Aitken basin hit the moon around 4 billion years old an is known as one of the largest impact craters ever known by the scientists. After looking at the data and the changes in the gravity from┬áNASA’s Gravity Recovery and Interior Laboratory (GRAIL) it was found that “When we combined that with lunar topography data from the Lunar Reconnaissance Orbiter, we discovered the unexpectedly large amount of mass hundreds of miles underneath the South Pole-Aitken basin,” James said. “One of the explanations of this extra mass is that the metal from the asteroid that formed this crater is still embedded in the Moon’s mantle.”
