Which is in fact the largest crater in our solar system?

Is it the 4000 km Valhalla multiring basin on Jupiter's moon Callisto ?


Internet searches always come up with the 2000 km Aitken basin on the farside of Earth's Moon

The actual crater inside Valhalla would be quite small. The north Mars lowlands basin - assuming it is impact-generated, which I think it is - is a true crater and a whopper. Next would be South Pole-Aitken on the Moon and Hellas, I suppose.

Incidentally, I am really sick of seeing the SPA basin referred to as "Aitken basin at the South Pole", or similar nonsense.
