Abstract

Periodic orbits are considered the "skeleton" of any dynamical system, because they present a lot of important information about the general behavior of the system. The motion of a dynamic system is said to be periodic when the same configurations are repeated at regular intervals of time, characterizing a collection of points that form a closed curve and that describe the solution to the problem. This project proposes a systematic analytical and numerical investigation, for mapping periodic solutions applied to the orbital dynamics of a space vehicle around asteroids and/or small bodies. Inserting the space vehicle into a periodic orbit, for observation and/or other purposes, is technically valid and economical, considering that the need for correction maneuvers will be minimal. The benefits resulting from these studies can be inserted in our society in the form of democratization and dissemination of scientific knowledge, as well as applications for communication, meteorology, exploration of the universe and observations of celestial bodies, for example. In addition, space agencies have included missions to small bodies in their programs, and the results of this project can be the basis of study for current and future missions. (AU)
