Several of the globular clusters found in the Milky Way may also have come from the Canis Major dwarf, which is expected to merge gradually with the Milky Way over about the next billion years. Canis Major Dwarf Galaxy. Called the Canis Major dwarf galaxy after the constellation in which it lies, it is about 25,000 light years away from the solar system and 42,000 light years from the center of the Milky Way. (2009). 2008). - The other two galaxies lie even closer to the milky way than the Magellanic Clouds, these two galaxies are known as Sagittarius Dwarf and Canis Major Dwarf. The Milky Way has more collisions in store. They were the closest known galaxies to the Milky Way until recently, when the Sagittarius and Canis Major dwarf galaxies were discovered and found to be even closer. 1993, Gilmore et al. Both are are in process of colliding with the Milky Way's disk. The Andromeda galaxy is 2.5 million light-years away and is moving closer to our galaxy for an eventual collision. In about 3 billion years, the Milky Way itself will be swallowed up, since it and the Andromeda galaxy are on a collision course. This is closer than the Sagittarius dwarf galaxy, discovered in 1994, which is also colliding with the Milky Way. and spiral arm populations of the MW and not by a collision with a dSph satellite galaxy. The center of this galaxy lies about 82,000 light-years from the Milky Way’s center. It is approximately 25,000 light years distant from Earth and 42,000 light years away from the Galactic Centre. Several of the globular clusters found in the Milky Way may also have come from the Canis Major dwarf, which is expected to merge gradually with the Milky Way over about the next billion years. In about 3 billion years, the Milky Way itself will be swallowed up, since it and the Andromeda galaxy are on a collision … Advertisement "Officially discovered in 1994, by Rodrigo Ibata, Mike Irwin, and Gerry Gilmore, Sagittarius Dwarf Elliptical Galaxy was immediately recognized as being the nearest known neighbor to our Milky Way at the time. Eventually, our galaxy will consume these and many other satellites, growing the Milky Way while shrinking the number of its companions. (2004a) as an excess in the density of Two Key words: Galaxy: stellar content – Galaxy: structure – stars: variables: other Online-only material: color figures 1. The Canis Major Dwarf is even closer (42,000 light-years away) and equally disturbed. •The dark matter density profile is the same for all dwarf galaxies (Walker et al. 2007, Strigari et al. dwarf galaxies, have ~107 M Sun of mass enclosed within the central 300 pc, independent of the dwarf galaxy’s luminosity (Mateo et al. The Canis Major Dwarf Galaxy (CMa Dwarf) is an irregular galaxy, roughly elliptical in shape, that is believed to be the nearest neighbouring galaxy to the solar system. Already long tidal tails have been stripped from this galaxy, which have wrapped themselves around the Milky Way three times. Identify the disk, bulge, halo, and spiral arms and indicates the galaxy… A Magellanic Collision Milky Way is being ‘twisted and deformed’ after a collision with another galaxy, scientists say. An example is the Canis Major dwarf galaxy, which has a mass of about 1% of the mass of the Milky Way. INTRODUCTION The Canis Major (CMa) overdensity was discovered by Martin et al. (Since 2003, the newly discovered Canis Major Dwarf Galaxy is considered the actual nearest neighbor).
