Abstract: A database with a high density of accurate distances is used to investigate the contributions to the motion of our Galaxy. It is found that the motion of the Local Group separates remarkably cleanly into 3 components: a large-scale attraction toward structure in the ‘Great Attractor’ sector, a midscale attraction toward the Virgo Cluster, and a local-scale ‘repulsion’ from the Local Void. These 3 components cause motions of comparable amplitudes and, conveniently, are directed almost orthogonal to one another.
