The unusual shape of the Moon given its present rotational and orbital state has been explained as due to a fossil figure preserving a record of remnant rotational and tidal deformation (Jeffreys, H. . Mem. R. Astron. Soc. 60, 187-217; Lambeck, K., Pullan, S. . Phys. Earth Planet. Interiors 22, 29-35; Garrick-Bethell, I., Wisdom, J., Zuber, M.T. . Science 313, 652-655). However, previous studies assume infinite rigidity and ignore deformation due to changes in the rotational and orbital potentials as the Moon evolves to the present state. We interpret the global lunar figure with a physical model that takes into account this deformation. Although the Moon deforms in response to rotational and orbital changes, a fossil figure capable of explaining the observed figure can be preserved by an elastic lithosphere.
