                         deste tipo possa passar de centenas de milh{\~o}es. O 
                         cintur{\~a}o de Kuiper cont{\'e}m pelo menos quatro regi{\~o}es 
                         dinamicamente distintas das quais a mais recentemente determinada

                         elemento. Gomes (2011) conseguiu reproduzir numericamente

                         entre as resson{\^a}ncias (Kozai+MMR) a part{\'{\i}}cula pode

                         estudar, atrav{\'e}s de uma metodologia num{\'e}rica e 
                         semi-anal{\'{\i}}tica, mecanismos din{\^a}micos tais como as 
                         resson{\^a}ncias de movimentos m{\'e}dios (MMR), a 
                         resson{\^a}ncia de Kozai e o acoplamento entre ambas. Em 
                         princ{\'{\i}}pio, os mesmos mecanismos que produzem 
                         \$2004XR_{190}\$ seriam capazes de gerar {\'o}rbitas de corpos 
                         pr{\'o}ximos a outras MMRs. Aqui pretende-se estudar estas 
                         possibilidades, a fim de realizar previs{\~o}es de 
                         poss{\'{\i}}veis {\'o}rbitas para corpos ainda n{\~a}o 
                         observados no cintur{\~a}o de Kuiper. ABSTRACT: More than one 
                         thousand transneptunian objects are currently known, but it is 
                         estimated that this number can be as big as hundreds of millions, 
                         The Kuiper Belt contains at least four dynamically distinct 
                         regions of which the rnost recently determined is the extended 
                         scattered disk (ESD), whose objects are also called detached 
                         objects. One of the objects belonging to this region, 2004XR190, 
                         has a peculiar orbit with small eccentricity and high inclination, 
                         suggesting that some dynamical process was responsible for the 
                         excitation of the latter element. Gomes (2011) was able to 
                         numerically reproduce orbits similar to those of 2004XR190 as the 
                         the result of scattering of the primordial planetesimals disk 
                         responsible for the migration of the giant planets in the early 
                         solar system. Through interactions between resonances (Kmmi+MMR) 
                         the particle could be detached from resonance after experiencing a 
                         low eccentricity mode resonance. In this thesis we intend to 
                         study, thraugh numerical and semi-analytical methods, mechanisms 
                         such as mean motion resonances (MMR), Kozai resonance, and the 
                         coupling between both. In principle, the same mechanism that 
                         produced \$2004XR_{190}\$ is capable of generating bodies dose 
                         to other MMR's. Here we intend to study this possibility in order 
                         to make predictions of possible orbits for bodies not yet observed 
                         in the Kuiper Belt.",
