Location
The Tucana Dwarf is located in the constellation Tucana. It is about 900 kiloparsecs (2,900 kly) away, on the opposite side of the Milky Way galaxy to most of the other Local Group galaxies and is therefore important for understanding the kinematics and formation history of the Local Group, as well as the role of environment in determining how dwarf galaxies evolve. It is isolated from other galaxies, and located near the edge of the Local Group.
The Tucana Dwarf galaxy is one of only two dwarf spheroidal galaxies in the Local Group that is not located near the Milky Way or the Andromeda Galaxy. It is therefore likely to have evolved in isolation for most of its history.
