What is the Sagittarius Dwarf Elliptical Galaxy?
The Sagittarius Dwarf Elliptical Galaxy is the third closest neighboring galaxy to the Milky Way Galaxy, which is where our solar system is located. At only 50,000 light years distant from the Milky Way’s core, the Sagittarius Galaxy is engaging in a polar orbit around the Milky Way, which is slowly devouring it. Even now, the Sagittarius Galaxy is leaking out a stellar stream, a filament which stretches around the Milky Way’s core like a gossamer loop. The Sagittarius Galaxy is named after the constellation where it can be found, Sagittarius. Discovered in 1994, the Sagittarius Dwarf Elliptical Galaxy is only about 10,000 light years in diameter, in comparison to the Milky Way’s diameter of 100,000 light years. The Milky Way Galaxy is estimated to be about 10,000 times more massive than the Sagittarius Galaxy. Up until 2003, it was thought to be the closest galaxy to the Milky Way, although this spot has recently been taken by the Canis Major Dwarf Galaxy, which is also being devoured
