{{main|Laniakea Supercluster}}
The proposed [[Laniakea Supercluster]] is defined as the Great Attractor's basin. It covers approximately four main galaxy superclusters, including superclusters of [[Virgo Supercluster|Virgo]] and [[Hydra–Centaurus Supercluster|Hydra–Centaurus]], and spans across 500&nbsp;million light years. Because it is not dense enough to be gravitationally bound, it should be dispersing as the universe expands, but it is instead anchored by a gravitational focal point. Thus the Great Attractor would be the core of the new supercluster. The local flows of the Laniakea supercluster converge in the region of the Norma and [[Centaurus Cluster|Centaurus Clusters]], approximately at the position of the Great Attractor.<ref>{{cite Q|Q28314882}}</ref>
