How quickly did the Moon form after the debris disk was established?
Answer
In a matter of hours to a few days
Unlike traditional models of planet formation that take millions of years to slowly aggregate matter, the Moon formed quite rapidly following the Giant Impact. The proximity of the debris disk to the Earth, combined with the hot, vaporous state of the material, allowed gravity to pull the particles together in a very short timeframe, potentially as quickly as a few hours to a few days. This rapid accretion explains why the Moon's orbital and compositional characteristics are so closely linked to the mantle of the early Earth.
