Galaxy X (galaxy)

Galaxy X[1][2] is a postulated dark satellite dwarf galaxy of the Milky Way Galaxy. If it exists, it would be composed mostly of dark matter and interstellar gas with few stars.[1][3] Its proposed location is some 90 kpc (290 kly) from the Sun,[1][3][4] behind the disk of the Milky Way,[1] and some 12 kpc (39 kly) in extent.[4] Galactic coordinates would be (l= -27.4°,b=-1.08°).[4]
