Entity: Canis Major Overdensity
Triple: [Milky Way subgroup, hasMember, Canis Major Overdensity]

The Canis Major Overdensity is a debated stellar overdensity near the plane of the Milky Way, often interpreted as either the remnant core of a disrupted dwarf galaxy or a warp/flare feature of the Galactic disk.
