Impact History of the Moon

Abstract

Establishing an absolute lunar impact chronology has important ramifications for understanding the early structure of the Solar System, to understand the evolution of both the dynamics and composition of the bodies. Our existing understanding of inner Solar System chronology is anchored to the crater density and analogy with impact flux rates on the Moon. The topic of lunar impact history has been the subject of numerous reviews (e.g., Hartmann et al. 2000; Ryder et al. 2000; Stöffler et al. 2006; Chapman et al. 2007; Fassett and Minton 2013; Bottke and Norman 2017; Zellner 2017...
