  Canis Major Dwarf
The authors find that this concentration is the nucleus of a dwarf galaxy which is in a progressive state of disruption, as it orbits our Milky Way Galaxy.
In many respects such as size, orbit and the process of dissolution, the Canis Major Dwarf is similar to SagDEG, which had been discovered in 1994 and taken the place as the nearest known neighbor for nine years.
Some Milky Way globular clusters are loosely grouped around the nucleus of the Canis Major dwarf, and at least some of them may have their origin in the halo of this small galaxy, and may represent the remnant of its former globular cluster system: M79, NGC 1851, NGC 2298, and NGC 2808.

  Canis Major Dwarf Galaxy - Wikipedia, the free encyclopedia
The Canis Major Dwarf Galaxy is located in the same part of the sky as the constellation of Canis Major.
The Canis Major dwarf galaxy is classified as an irregular galaxy and is now thought to be the closest neighbouring galaxy to the Milky Way, being located only 42,000 light-years from the Galactic Center and approximately 25,000 light-years away from our Solar System.
It is thought that the open clusters may have formed due to the dwarf galaxy's gravity perturbing material in the galactic disk and stimulating star formation.

Galaxies come in many different shapes: some are spherical, some are sort of blobby and disorganized, and some are disk-shaped, with elegant spiral arms of young stars radiating out from their centers.
This galaxy was dubbed the Sagittarius Dwarf galaxy (as it, and the core of the Milky Way, lie in the constellation Sagittarius), and until recently, it held the record for the nearest galaxy, at about 70,000 light away.
The Canis Major dwarf galaxy is not faring well in its gravitational battle with the Milky Way, and there are streamers of stars being pulled off the smaller galaxy onto the disk of our own.

The team of five astronomers found the dwarf galaxy by sifting through data on millions of stars collected by the Two Micron All Sky Survey (2MASS), which recently surveyed the entire sky at three near-infrared wavelengths with 1.3-meter telescopes in Arizona and Chile.
Unlike the Sagittarius dwarf galaxy, which is moving nearly perpendicular to the Milky Way’s disk, the Canis Major dwarf galaxy and the ring are moving nearly in the same plane as the disk.
The Canis Major dwarf appears to contain about 1 billion solar masses and is thus adding nearly 1 percent to the mass of the Milky Way.

 The Milky Way Galaxy
As a galaxy, the Milky Way is actually a giant, as its mass is probably between 750 billion and one trillion solar masses, and its diameter is about 100,000 light years.
The Milky Way Galaxy belongs to the Local Group, a smaller group of 3 large and over 30 small galaxies, and is the second largest (after the Andromeda Galaxy M31) but perhaps the most massive member of this group.
M31, at about 2.9 million light years, is the nearest large galaxy, but a number of faint galaxies are much closer: Many of the dwarf Local Group members are satellites or companions of the Milky Way.
