Lunar Formation Model Landscape

Numerous models have been proposed to explain the origin of the Moon.

Each model attempts to satisfy a combination of dynamical, compositional, isotopic, and orbital constraints.

Model Diversity

The existence of multiple competing models demonstrates the complexity of the Earth–Moon system.

Earth: Day Zero does not begin by selecting among these models.

Framework Position

The reconstruction evaluates models according to their ability to satisfy observed constraints rather than their historical popularity.
