abstract = "Space missions to visit the natural satellite of Jupiter, Europa,
constitute an important topic in space activities today, because
missions to this moon are under study now. Several considerations
have to be made for these missions. The present paper searches for
less perturbed circular orbits around Europa. This search is made
based on the total effects of the perturbing forces over the time,
evaluated by the integral of those forces over the time. This
value depends on the dynamical model and on the orbit of the
spacecraft. The perturbing forces considered are the third-body
perturbation that comes from Jupiter and the J 2, J 3, and C 22
terms of the gravitational potential of Europa. Several numerical
studies are performed and the results show the locations of the
less perturbed orbits. Using those results, it is possible to find
near-circular frozen orbits with smaller amplitudes of variations
of the orbital elements.",
