Description

Both NGC 185 and NGC 147 lie about 7 degrees north of M31 in Cassiopeia.Like M31 and its better-known companions, each of these dwarf galaxies lie about 2 million light years away, about the same distance as M31 itself. The galaxies likely revolve around each other as a binary system, and the pair itself revolves around the much larger M31. Each is about 1/10 the diameter of its parent galaxy. And each is about the same size and shape as Andromeda's more famous companions.
