ABSTRACT:
In this paper we focus on the dynamics of a solar sail in the vicinity of the La-
grangian points L4/L5. These points are linearly stable and so are the families of
quasi-periodic orbits around them. Moreover, there is a region of effective sta-
bility around them, where the trajectory of a satellite will remain there for more
than 1000 years. We will describe these regions and see how they are affected by
the solar radiation pressure. A good understanding of these regions and of how to
reach them would enable a novel space weather mission
