Rethinking the Moon

The Moon retains clues to the formation and earliest evolution of the Solar System. In this talk I’ll discuss three issues that are being re-addressed in the light of new data and theories: how the Moon formed; when it formed; and how asymmetric it is. I’ll also pay attention to how predictions might be tested with upcoming or active lunar missions.
