Numeric ring-reconstructions based on massifs favor a non-oblique south pole-Aitken-forming impact event

•Three numeric fits of 201 massifs we identify as likely SPA-ring remnants.•Different fit variants all give outer and inner ellipses with ellipticities ≤ 1.06.•Near-circular SPA would have required impact at non-oblique angle of well over 44°.•≤20% increased impact melt volume, excavation depth, and...
