===Consequences for the Coaccretion Hypothesis===

This model does not require low probability events to occur, in contrast to the Capture model and provides a cogent explanation as to why the Earth and Moon share a common oxygen isotope composition. However, there are unanswered questions regarding the angular momentum of the two bodies, and the observed lack of iron in the Moon counts against it, as well.(It should be mentioned that there have been attempts to address this problem recently, see [[#Current Status|Current Status]].).<ref name="Nova1"/>
