[edit] Galaxy group information
NGC 7793 is one of the brightest galaxies within the Sculptor Group, a group of galaxies in the constellation of the same name. The group itself is an elongated, loosely bound group of galaxies with the Sculptor Galaxy (NGC 253) and its companion galaxies forming a tightly-bound core of galaxies near the center.[2]
