How deep does the South Pole–Aitken basin plunge below the surrounding plain?
Answer
Over 8 kilometers (5 miles).
The vertical relief of the South Pole–Aitken basin is staggering, with measurements indicating that it extends downward more than 8 kilometers, or 5 miles, below the elevation of the adjacent plains. To contextualize this extreme excavation, this vertical depth is comparable to the height of Mount Everest when measured from sea level on Earth, demonstrating the massive volume of material removed during the impact.
