The Sagittarius Dwarf Elliptical Galaxy (Sgr dE) is an elliptical satellite galaxy of the Milky Way consisting of four globular clusters, the main cluster discovered in 1994. It is 10,000 light-years in diameter and 65,000 light-years from Earth, in a polar orbit about 50,000 light-years from the Milky Way core. It is currently the 2nd nearest known galaxy to the Milky Way after the Canis Major Dwarf Galaxy. Characteristics:
