Clusters of galaxies form due to the gravitational attraction between individual galaxies in a region of space. Over time, these galaxies are pulled together by their mutual gravity to create a cluster structure. The largest clusters are held together by dark matter, which provides the majority of the mass in the system.
A supercluster.
galaxies are in every direction in space there in clusters and super clusters
galaxies
A collection of galactic groups form a cluster of galaxies. A supercluster is the largest known structure. Galaxies can exist outside of a group or cluster, but the estimated amount is only about 5%. However, there is a possibility that these galaxies may have interacted or merged with other galaxies in the past,

The galaxy clusters are the solar systems orbiting the galaxies.
They form galaxies, galactic clusters, and galactic superclusters.
Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.

All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
