False Clusters
Sometimes clusters are put forward that are not genuine clusters or superclusters. Through the researching of member positions, distances, peculiar velocities, and binding mass, former clusters are sometimes found to be the product of a chance line-of-sight superposition.
| Former cluster | Notes |
|---|---|
| Cancer Cluster | The Cancer Cluster was found to be a random assortment of galaxy groups, and not a true cluster. |
| Coma-Virgo Cloud | The early identification of the Coma-Virgo Cloud of Nebulae was actually a mistaken identification due to the superposition of the Virgo Supercluster and Coma Supercluster, and not a Coma-Virgo Supercluster |
