[9] This object is located 14′ east of the core of the large Coma Cluster of galaxies,[5][10] at a distance of 330 million light-years (100 Mpc) from the Milky Way.

[4] With a combined apparent visual magnitude of 13.20, it is the fifth brightest galaxy within a degree of the cluster core.

[8] The morphological classification of IC 4051 is E2, indicating a slightly oval-shaped elliptical galaxy.

[11] IC 4051 has an unusually large population of globular clusters, comparable to a Type-cD galaxy.
