Tidally interacting galaxies offer an interesting held for the investi
gation of chaotic phenomena in stellar systems. When the galaxies are
gravitationally bound, and one of them is much larger than the other,
the latter can be regarded as a satellite of the former. The study of
their dynamics is somewhat simplified in this case, which presents wel
l observed examples in nature (e.g., globular clusters). Galactic sate
llites suffer orbital decay due to dynamical friction, a process that
may be greatly enhanced in the presence of chaotic motions. Besides, t
he satellite is stripped by the field of tidal forces and, in the long
run, it will disintegrate completely Modern observations are able to
show the signature of these processes taking place at present.
