The Canis Major Dwarf Galaxy, or the CMa Dwarf in short, or the Canis Major Overdensity or CMa Overdensity, is a disputed dwarf irregular galaxy located in the Local Group and the constellation Canis Major. The believed small galaxy contains a relatively high percentage of red giants, and is thought to contain an estimated billion stars. It is classified as an irregular galaxy and is believed the closest neighbouring galaxy to the Earth's location in the Milky Way, being located about 25,000 light-years (7.7 kiloparsecs) away from the Solar System[2] and 42,000 ly (13 kpc) from the Galactic Center.
