collection of galaxies comparison table

Subject has number of galaxie has definition has synonym has number of cluster

binary galaxy 2 Two galaxies orbiting each other owing to their mutual gravitational attraction. double galaxy

galaxy cluster 10² to 10³ (order of magnitude) An aggregate of galaxies. Bautz and Morgan divide them into three morphological types: type I contains a supergiant cD galaxy; Coma is type II, type III contains no members significantly brighter than the general bright population. Virgo is type III. 21 known X-ray sources are associated with clusters of galaxies.

Great Wall A sheet of galaxies which stretches more than 500 million light-years across the sky.

hypergalaxy A system consisting of a dominant spiral galaxy surrounded by a cloud of dwarf satellite galaxies, often ellipticals.

supercluster A cluster of clusters of galaxies. Superclusters are typically about one hundred million (10⁸) light-years in diameter and contain tens of thousands of galaxies.
