Although the majority of gravitational effects can be dis-cussed using approximations and numerics, a systematic study of all effects can onlybe achieved by using analytical methods. In particular, exact analytic treatmentscan finally answer the question whether the cosmological expansion, modeled hereby a cosmological constant, has an observable influence on effects as the Pioneeranomaly or the creation of gravitational waves.This thesis is devoted to the study of the geodesic motion in space-times witha nonvanishing cosmological constant using analytical methods. In each space-timeconsidered here, the discussion of geodesics takes place on two different levels: Thefirst is the classification of orbits in terms of the black hole and test particle orlight parameters.
