Satellite Galaxies All in a Row—How So?
One theory is that the galaxies in the cluster are arranged in a filamentary structure, with the satellite galaxies forming a line along the filament. Another theory is that the galaxies in
the cluster are arranged in a spherical structure, with the satellite galaxies forming a halo around the main galaxy.


Satellite galaxies are those that orbit around larger galaxies. They are often found in clusters of galaxies, where they are arranged in rows. The reason for this arrangement is not yet fully understood, but scientists believe that it may be due to gravitational interactions between the galaxies in the cluster.
