The Eridanus II Dwarf is a low-surface brightness dwarf galaxy in the Eridanus constellation. It was independently discovered by two teams of astronomers in 2015, using data from the Dark Energy Survey. The stability of this star cluster, near the center of such a small, diffuse, galaxy, places constraints on the scientific nature of dark matter.
