Abstract
This thesis explores the unique properties of the classical Kepler problem, including Bertrand's theorem, the connection between Kepler and harmonic oscillator potentials, and the existence of an additional conserved quantity  the LaplaceRungeLenz (LRL) vector. The role of symmetries in this context is explored. Then a comprehensive proof of Moser's construction, establishing the correspondence between nonconstant geodesics on an ndimensional sphere and Kepler orbits with negative energies in ndimensions, is presented. This construction demonstrates that the Kepler problem has a larger symmetry group compared to an arbitrary central potential. The relativistic corrections to twobody problems, which generically induce perihelion precession, are then investigated. Notably, a specific relativistic system involving an extremal test particle near an oppositely charged extremal EinsteinMaxwelldilaton black hole does not exhibit perihelion precession. However, this phenomenon is limited to a specific value of the dilaton coupling constant, specifically a=\sqrt{3}. A generalized theorem based on this construction is established, followed by an examination of cases where a\neq \sqrt{3}. It was shown that away from a=\sqrt{3}, the testparticle orbits correspond to the orbits of a perturbed Kepler problem.
