\maketitle





Laskar et al. (1993) have globally analysed the stability of the planetary obliquities in a conservative framework. In the present work, the same model is extended by adding disspative effects in the Earth--Moon system. Some new results on the long term evolution of the spin of the Earth will be presented.
