Diagram showing the interior of the Earth's Moon. The outermost layer, the crust, is about 45 miles (70 km) thick. This is thicker than the Earth's crust, which cooled down at a much slower rate. Beneath the crust is a thick mantle extending to a depth of about 620 miles (1000 km). Moonquakes probably originate here. And finally at the very centre is a small core, less than four per cent of the Moon's mass. It may be partially molten.
