The  moon

                               Crust:                            

Surface of moon is dry, dusty and rocky. The thickness of rock crust is about 37 miles (60 km) on the side face to Earth andit is in the opposite side. This thickness is about 62 miles (100 km)

NASA'S Apollo mission says the formation of moon occurred about 4.3 billion years ago (about 60 million years after formation of Earth).

           Rigid lithosphere mantle:            

This is a rock layer which is not that much hot to flow and it's thickness is about 620 miles (1000 km).

                  Non-rigid mantle:                  

This is a asthenospheric layer and only the deepest parts of that are hot enough to flow and it's rigidity is less than lithosphere but can transmit seismic waves.

                              Core:                            

This is non-fluid and probably made of iron-rich rock which is only 2 to 4 percent of total mass of Moon and it's diameter may be is around 225 miles on 360 km.
