The effectiveness of this type of maneuver has been proven since the beginning of space exploration. According to this premise, we have explored the existence of a natural and direct link between low Earth orbits and the lunar sphere of influence to get low-energy transfer trajectories to the Near Earth Objects (NEOs) 99942 Apophis, 1994 WR12, and 2007 UW1 through swing-bys with the Moon. The existence of this link is related to a family of retrograde periodic orbits around the Lagrangian equilibrium point L1 predicted for the circular, planar, restricted three-body Earth-Moon-particle problem. The trajectories in this link are sensitive to small disturbances. This enables them to be conveniently diverted reducing so the cost of the swing-by maneuver. These maneuvers allow a gain in energy sufficient for the trajectories to escape from the Earth-Moon system and to stabilize in heliocentric orbits between the Earth and Venus or Earth and Mars. Therefore, the trajectories have sufficient reach to intercept the NEOs' orbits. %@mirrorrepository sid.inpe.br/mtc-m19@80/2009/08.21.17.02.53 %T Alternative Transfers to the NEOs 99942 Apophis, 1994 WR12, and 2007 UW1 via Derived Trajectories from Periodic Orbits of Family G %@electronicmailaddress UNESP, Brazil %@secondarytype PRE PI %@usergroup administrator %@usergroup marciana %@group %@group LAC-CTE-INPE-MCT-BR %3 303604.pdf %@secondarykey INPE--PRE/ %@issn 1024-123X %@issn 1563-5147 %2 sid.inpe.br/mtc-m19/2010/09.01.18.03.29 %@affiliation %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Mechanical engineering Schol, state university of Sao Paulo at Guaratinguetá, Brazil %B Mathematical Problems in Engineering %@versiontype publisher %4 sid.inpe.br/mtc-m19/2010/09.01.18.03 %@documentstage not transferred %D 2009 %V Article ID 303604 %@doi 10.1155/2009/303604 %A Melo, Cristiano Fiorilo de, %A Macau, Elbert E.
