Abstract. We review some results concerning perturbation techniques
applied to the spin--orbit problem. In particular, we start by
constructing periodic orbits by means of a combination of the
implicit function theorem and of perturbation theory. Next, we focus on
rotational and librational invariant tori, whose existence is proved
by KAM theory. Applications to the Moon and Mercury are presented.
This paper is the text of an invited lecture at the meeting
"The rotation of celestial bodies" in honor of Jacques Henrard.
