SCIENTISTS HAVE DATED THE MOON’S OLDEST AND LARGEST IMPACT SITE
WORDS STEFANIE WALDEK
For billions of years, our celestial neighbour has been absolutely bombarded by asteroids and comets, and the assault has left behind a heavily pockmarked surface. The largest and oldest known impact site on the Moon is the South Pole-Aitken basin, stretching across nearly 1,250 miles of the far side of the Moon. Thanks to new research, scientists have dated the impact to a period between 4.32 and 4.33 billion years ago.
