The Sagittarius Dwarf Spheroidal Galaxy is a small galaxy located about 70,000 light-years from Earth. It is part of the Milky Way galaxy and is classified as a spheroidal galaxy due to its round shape and low luminosity. This galaxy is primarily composed of older stars and contains very little gas and dust, making it less active in star formation compared to larger galaxies. Discovered in 1994, the Sagittarius Dwarf Spheroidal Galaxy is currently being disrupted by the gravitational pull of the Milky Way. As it orbits our galaxy, it is gradually losing stars, which contributes to the formation of the Milky Way's halo. This interaction provides valuable insights into galaxy formation and evolution.
