Displaced solar sail orbits : dynamics and applications [PDF]
, 2010 We consider displaced periodic orbits at linear order in the circular restricted Earth-Moon system, where the third massless body is a solar sail. These highly non-Keplerian orbits are achieved using an extremely small sail acceleration.
