What is the largest crater on the Moon?
The largest known impact crater on the Moon is over 1,300 miles across. It is called the South Pole-Aitken basin because it stretches from the south pole of the Moon to the Aitken crater on the far side of the Moon. The crater was formed when a large object, the size of an asteroid or comet, crashed into the Moon’s surface. The false-color image on the right shows the lowest parts of this impact crater as purple. Higher regions are shown as blue, and the highest areas are shown as yellow and red. The image is from the Clementine spacecraft.
