Perseus cluster comparison table

Subject has number of galaxie is part of is a kind of has redshift is an instance of has mass has definition has brightest member

galaxy cluster 10² to 10³ (order of magnitude) collection of galaxies 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.

Perseus cluster 500 Local Supercluster z = 0.0183 galaxy cluster 2 × 10¹⁵ M_sun A diffuse, irregular cluster (richness class 2) dominated by and centered on the Seyfert galaxy NGC 1275 (Perseus A). Mass required to bind the cluster, greater than 10¹⁵ M_sun. NGC 1275
