Abstract

Quasihalo orbits are Lissajous trajectories librating about the well known
halo orbits. The main feature of these orbits is that they keep
an exclusion zone in the same way that halo orbits do. As a result, the
knowledge of this type of orbit, gives more flexibility to the
mission analysis design about collinear libration
points of any pair of primaries in the solar system.
