摘要: The Apollo-derived tenet of an anhydrous Moon has been contested following measurement water in several lunar samples that require to be present the interior. However, significant uncertainties exist regarding flux, sources and timing delivery Moon. Here we address those fundamental issues by constraining mass accreted modelling relative proportions asteroidal cometary for are consistent with measured isotopic compositions samples. We determine a combination carbonaceous chondrite-type materials were responsible majority (and nitrogen) delivered Earth-Moon system. Crucially, conclude comets containing enriched deuterium contributed significantly <20% Therefore, our work places important constraints on types objects impacting ∼4.5-4.3 billion years ago origin inner Solar System.
