The Sagittarius Dwarf Spheroidal Galaxy (Sgr dSph), also known as the Sagittarius Dwarf Elliptical Galaxy (Sgr dE or Sag DEG), is an elliptical loop-shaped satellite galaxy of the Milky Way. It contains four globular clusters in its main body, [8] with the brightest of them — NGC 6715 (M54) — known well before the discovery of the galaxy ...
The Sagittarius Stream is a stream of stars in polar orbit around the Milky Way leeched from the Sagittarius Dwarf. The Virgo Stellar Stream is a stream of stars that is believed to have once been an orbiting dwarf galaxy that has been completely distended by the Milky Way's gravity.

Canis Major Dwarf Galaxy: Milky Way Galaxy: The Monoceros Ring is thought to be the tidal tail of the disrupted CMa dg. [citation needed] Virgo Stellar Stream: Milky Way Galaxy: This is thought to be a completely disrupted dwarf galaxy. [citation needed] Sagittarius Dwarf Elliptical Galaxy: Milky Way Galaxy: M54 is thought to be the core of ...
Previously thought to belong to the Milky Way at a distance from Earth of about 50,000 light-years, it was discovered in 1994 that M54 most likely belongs to the Sagittarius Dwarf Elliptical Galaxy (SagDEG), [9] making it the first globular cluster formerly thought to be part of our galaxy reassigned to extragalactic status, even if not ...
In astronomy, the Sagittarius Stream is a long, complex structure made of stars that wrap around the Milky Way Galaxy in an orbit that nearly crosses the galactic poles.It consists of tidally stripped stars from the Sagittarius Dwarf Elliptical Galaxy, resulting from the process of merging with the Milky Way over a period of billions of years.
Although not visible to the naked eye, Sagittarius A* is located off the top of the spout of the Teapot asterism. [1] The Sagittarius Dwarf Elliptical Galaxy is located just outside the Milky Way. Baade's Window is an area with very little obscuring dust that shows objects closer to the Milky Way's center than would normally be visible.
The Magellanic Clouds (Magellanic system [2] [3] or Nubeculae Magellani [4]) are two irregular dwarf galaxies in the southern celestial hemisphere. Orbiting the Milky Way galaxy, these satellite galaxies are members of the Local Group. Because both show signs of a bar structure, they are often reclassified as Magellanic spiral galaxies.
