The Origin of the Moon and the Core of the Earth
The possibility is here considered that the formation of the Earth’s core increased the rotational instability of the Earth and led to the formation of the Moon. Earlier work by Jeans leads to the conclusion that the formation of the core would stabilize the Earth; later work by P. H. Roberts indicates that the contrary is true and in fact that core formation tends slightly to destabilize the Earth. It is shown that the heating effects of core formation have a negligible effect on the Earth’s stability.
