one such frame of reference is the hubble flow, the apparent motions of galaxy clusters due to the expansion of space. individual galaxies, including the milky way, have peculiar velocities relative to the average flow. thus, to compare the milky way to the hubble flow, one must consider a volume large enough so that the expansion of the universe dominates over local, random motions. a large enough volume means that the mean motion of galaxies within this volume is equal to the hubble flow. astronomers believe the milky way is moving at approximately with respect to this local co-moving frame of reference. the milky way is moving in the general direction of the great attractor and other galaxy clusters, including the shapley supercluster, behind it. the local group (a cluster of gravitationally bound galaxies containing, among others, the milky way and the andromeda galaxy) is part of a supercluster called the local supercluster, centered near the virgo cluster: although they are moving away from each other at as part of the hubble flow, this velocity is less than would be expected given the 16.8 million pc distance due to the gravitational attraction between the local group and the virgo cluster.
