Impact Basins and the Moon: Understanding Very Large Crater Formation
Impact basins are the largest type of impact structure in the Solar System, but also the rarest and least understood. The Moon's surface shows evidence of at least 40-50 of these basins (impact structures greater than 300 km in diameter), some of which are fairly well-preserved. Here, numerical modeling is used to investigate the formation and structure of these basins. The modeling constrains impact conditions for two of the largest basins, South Pole-Aitken and Orientale, highlights similarities between basin and smaller-scale crater formation, and demonstrates the great importance of target temperature on the basin formation process.
