Sagittarius Dwarf Elliptical Galaxy Flag
This galaxy is one of the closest galaxies next to us. Some think it is an extension of the Milky Way.
In a certain way it is like a 'galactic moon' of the Milky Way. In total we have found about 12-15 satellite galaxies that hover us. You could even call them either a Gloonexy, Gmoonexy, or something else?
The Sagittarius Dwarf Elliptical Galaxy is a relatively new to our awareness, since it was discovered in 1994, after the rise of the Internet. It's only 20 kilo-parsecs away.
