abstract = "An integral index is used in this manuscript to search for the
least gravitationally perturbed orbits around an oblate spheroid.
Although there are missions where perturbations are desired, such
as Sun-synchronous orbits, near Keplerian orbits can be useful in
some cases during the whole mission or partially, helping to keep
the oscillations of the orbital parameters in the minimum possible
level, which can be interesting to observe celestial bodies. These
orbits are also good candidates to require a lower number of
station-keeping maneuvers, helping to simplify the logistic of the
mission. The index used is available in the literature and it is
based on the integration of the accelerations suffered by a
spacecraft over time. An oblate spheroid is used to represent the
approximate shape of non-spherical bodies because it has a closed
equation for the potential, which makes it ideal for the analysis
proposed, and because it is a shape similar to what is found for
several objects in the small bodies population. The Lagrange
planetary equations are also used to map orbits that have a
minimum rate of variation in their orbital elements, and compared
with the results obtained with the integral index. The results
show a very good agreement between the index and the variations of
the orbital elements of the spacecraft, in particular in terms of
locating the least perturbed orbits to place the spacecraft.",
