How does the depth of the relatively fresh Tycho Crater compare to the SPA Basin?

Answer

Tycho Crater's depth is measured in the few kilometers range, dwarfed by the ancient SPA feature

When comparing the South Pole-Aitken Basin (SPA) to younger craters on the Moon, the difference in scale and depth is dramatic. Features like Tycho Crater, which is renowned for its sharp morphology and bright ray system, have depths that are typically measured only in the few kilometers range. This relatively shallow depth is completely dwarfed by the SPA Basin, whose central floor drops approximately 13 kilometers below the surrounding terrain. The vast disparity highlights the effects of billions of years of subsequent seismic activity and further impacts, which have modified the original profile of the ancient SPA structure, while younger craters retain their initial sharpness.
