ABSTRACT: 
In this work we are interested in the local dynamics around a
Halo-type orbit for a solar sail and how it varies when the sail
orientation changes. To model the dynamics of a solar sail we have
considered the Restricted Three Body Problem adding the solar
radiation pressure (RTBPS). We know that the RTBPS has a 2D family of
equilibrium points parametrised by the two angles that define the sail
orientation.  First we will describe the families of periodic and
quasi-periodic orbits that appear around the different equilibrium
points. We will find planar, vertical and Halo-type orbits around the
different equilibria. Finally, we will focus on a Halo-type orbit and
describe the natural dynamics around it.  We will discuss the
possibility of using this knowledge to derive station keeping
strategies for a solar sail.
