At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs (110 million light-years).

Galaxy clusters are much larger than galaxy groups, such as the Local Group.

Recently, much work has been done on the effects of these objects on the intergalactic medium, particularly in galaxy groups and clusters.

They used to be bright, anyway..." Spinner made out the central galaxy group.

These are the brightest members of two respective subgroups within the galaxy group, and are heading toward a merger in the future.

Such events are frequent among the galaxies in galaxy groups.

It is probably in the same galaxy group as NGC 2935.

Galaxy motion is also influenced by galaxy groups and clusters.

Galaxy clusters are much larger than galaxy groups.

The brightest member in this galaxy group is questionable and partly depends on the analysis used to determine group members.
