Lunar Rotation

Before discussing its cause, one must be clear in exactly what respect the lunar figure deviates from the equilibrium one. This is necessary because there has been confusion over the question for a long time. It was known early that the Moon’s ellipsoid of inertia is triaxial and that the differences of the principal moments of inertia determined from observations are several times larger than the theoretical values corresponding to hydrostatic equilibrium. The stability of lunar rotation requires that the axis of least moment of inertia point approximately towards the Earth and the laws of Cassini show that it is really so.

The basic idea of this project is to introduce a senior student to an astronomical phenomenon that he analyses carefully and simulates on the graphic screen of a personal computer. In a second step, this simulation serves as a demonstration for junior students.Three examples are presented here: the retrograde motion of the planets, the Earth’s rotation, and the precession and the equilibrium figure of the Earth due to tides. Programs have been written on an IBM PC/AT.It would be highly desirable to start an exchange program of material of didatic interest among the international astronomical community

Gravity and heat flow observations indicate that the structural and chemical differences between oceanic and continental regions extend to depths of several hundred kilometres. A theory of continental drift must account for the maintenance of the deep structure of continents. A comparison of the figure of the Earth obtained from satellite observations with that calculated on the assumption that the Earth is in hydrostatic equilibrium demonstrates that stress differences of the order of 100 bars exist within the mantle. If these stress differences are to be maintained by convective flow, then the mantle must have an average viscosity of 1026 c.g.s.
