Abstract

We consider the Kepler two-body problem in the presence of a cosmological constant [Formula: see text]. Several dimensionless parameters characterizing the possible orbit typologies are used to identify open and closed trajectories. The qualitative picture of the two-body motion is described and critical parameters of the problem are found.
