Solid rocky and dusty crust with solid and semi solid mantle and inner core and fluid iron outer core with lots of craters on its surface which were created by heavy bombardments from meteors and comets over a period of time . A question arises that if our moon had a fluid iron outer core then what about the magnetic fields of the moon why moon doesn’t generate magnetic fields? That is due to the much cooler mantle and the lack of atmosphere on moon because of which there is no protection to the solar winds which are a stream of charged particles and free electrons and protons made of plasma. But how was our moon formed and how did it reached there in its set orbit like it revolves now? The answer lies 4.5 billion years ago when our solar system was beginning to take its shape.
