Abstract
After a brief presentation of the properties of the giant planets, we will describe their satellite populations, focusing on the so-called " irregular "satellitesdue to their eccentric and inclined orbits, probably captured from the protoplanetary disk. We will also examine the dynamical properties of Trojans, objects sharing the orbits of Jupiter or Neptune and oscillating around the equilibrium points discovered by J.-L. Lagrange.
