The Monoceros Ring is a proposed ring of stars around the Milky Way which consists of a stellar stream torn from the Canis Major Dwarf Galaxy as it merges with the Milky Way over the course of billions of years. It is a complex ringlike structure which wraps around our galaxy three times, formed from the long filament of stars pulled from the Canis Major Dwarf Galaxy by tidal forces as it orbits the Milky Way. The ring has a mass of 100 million solar masses and is 200,000 light years long.
