The Cepheus Dwarf Galaxy is a small, irregular galaxy located in the constellation Cepheus. It is part of the Local Group, which includes the Milky Way and Andromeda galaxies. Discovered in 1999, it is about 2.4 million light-years away from Earth and has a low surface brightness, making it difficult to observe. This galaxy is primarily composed of old stars and contains very little gas and dust, which limits new star formation. The Cepheus Dwarf Galaxy is thought to be a satellite of the Milky Way, and its study helps astronomers understand the formation and evolution of smaller galaxies in the universe.
