This is the largest impact crater in the Solar System and is located on our own natural satellite.

The Aitken basin is a gigantic impact scar in the lower southern hemisphere of the far side of the Moon, and It is the largest crater in the Solar System (that we know of).

The basin measures about 2,500 kilometers in diameter and, with a depth of 13 kilometers, is also the deepest impact crater.

Geological accidents

Despite the fact that this gigantic crater has existed for about 3.9 billion years, we were not aware of its existence until 1959, when the Soviet space probe Luna 3 made the first photographs of the far side of the Moon.

The crater was so designated in memory of Robert Grant Aitken, an American astronomer who specialized in binary star systems.

The Moon has only been stepped on by 12 people, and the last man to step on this satellite was Gene Cernan, Commander of Apollo 17, on December 14, 1972.

The largest impact crater on Earth is the Vredefort Crater near Johannesburg in South Africa, with a diameter of 300 kilometers.
