The Canis Major dwarf galaxy is an irregular dwarf galaxy which neighbors the Milky Way and belong to the Local Group. It contains about one billion stars with high percentage of red giant stars. Canis Major dwarf galaxy is located about 25,000 light-years away from our Solar System.
The Canis Major dwarf galaxy main body is degraded and tidal disruption causes a long filament of stars to trail behind it as it orbits the Milky Way. It forms a complex ringlike structure sometimes referred to as the Monoceros Ring which wraps around our galaxy three times.
