Canis Major Dwarf galaxy. Classified as a K1III yellow/orange giant, it has a gas giant planet in orbit around it 2.6 times the size of Jupiter.

Recent observational evidence suggests that the Sagittarius dwarf galaxy represents the only major ongoing accretion event in the Galactic halo, accounting for the majority of stellar debris identified there. The galaxy is believed to be a satellite of the Milky Way and a member of the Local Group of galaxies, which includes about 30 galaxies that are loosely bound together by their gravitation. The galaxies in the Local group take up a region of space about 10 million light-years across. Some of the dwarf galaxies orbiting the Milky Way are Canis Major Dwarf (the closest), Sagittarius Dwarf Elliptical Galaxy, Ursa Minor Dwarf, Sculptor Dwarf, Sextans Dwarf, Fornax Dwarf, and Leo I Dwarf. Other deep sky objects in Canes Venatici include the dwarf elliptical galaxy NGC 4627, the elliptical galaxy NGC 5223, the lenticular galaxy NGC 4138, the edge-on spiral galaxies NGC 4244 and NGC 4217, the spirals NGC 5002, NGC 5112, and NGC 4534, and the dwarf spheroidal galaxies Canes Venatici I and Canes Venatici II. – Canis Major Dwarf Galaxy, discovered in the year 2003, contains about a billion stars, and at 25,000 light years distant is now believed to be the closest galaxy to our solar system, although its galaxy status is still disputed.
NU02 Canis Majoris is bright enough at magnitude 3.95 to be easily seen with the naked eye. Either way, it is clear that this bunch of stars has been pulled very close to our Milky Way by our galaxy’s massive gravity. In 2003 a team of International astronomers discovered an even closer galaxy, the Canis Major dwarf galaxy. The smallest dwarf galaxies of the Milky Way are only 500 light-years in diameter. Each galaxy in the Local Group has its own size, shape, and defining characteristics. Canis Major Dwarf. Canis Major Dwarf and Monoceros Ring. A small, irregular galaxy with a mass of about a billion solar masses, the Canis Major dwarf galaxy is one of our closest neighbours, lying approximately 25,000 light years from the Sun and 42,000 light years from the centre of the Milky Way.Until recently, however, this dwarf galaxy lay unobserved behind the dust and gas in the disk of the Milky Way. Another dwarf galaxy surrounding the Milky Way is the Sagittarius Dwarf. The Canis Major dwarf galaxy (CMa dwarf) or Canis Major overdensity (CMa overdensity) is a disputed dwarf irregular galaxy in the Local Group.It is in the same part of the sky as the constellation Canis Major.. The Canis Major Dwarf Galaxy Dwarf Galaxy is believed to contain one billion stars in all, a relatively high-percentage of which are in the Red Giant Branch phase of their lifetimes. Canis Major Dwarf Galaxy Messier 79. The supposed small galaxy contains a relatively high percentage of red giant stars, and is thought to contain an estimated one billion stars in all. This paper summarises the recent discovery of another potential Milky Way accretion event, the Canis Major dwarf galaxy. It’s now seen an elongated tidal stream around our galaxy and sits at about 70,000 light years away from the Sun.

Canis Major contains eight stars known to support planetary systems. It has the designation NGC 1904 in the New General Catalogue. Instead they think it is just a dense area of faraway stars that are still part of the Milky Way. A dwarf galaxy remnant in Canis Major… These include Carina Dwarf, Draco Dwarf, and Leo II Dwarf. Astronomy Picture of the Day (APOD) November 23, 2003. And, the group is actually part of an even larger group of galaxies known as the Local Supercluster. It was discovered in 1994 and just like the Canis Major dwarf galaxy, the massive pull of the Milky Way’s gravity has been tearing it apart over billions of years. It lays at about 42.000 light years from the Milky Way’s center and 25,000 light years from Earth.
A Japanese cargo ship arrived at the International Space Station today (May 25) to make one final delivery before its fleet is retired. The Canis Major dwarf is classified as an irregular galaxy. Canis Major Dwarf: A New Closest Galaxy. Some scientists don’t think the Canis Major cluster of stars is actually its own galaxy or dwarf galaxy.
Unlike Sagittarius, which is contributing to the Galactic halo, the location and eventual demise of Canis Major suggests that it represents a building block of the thick disk.
Canis Major is a constellation in the southern celestial hemisphere.In the second century, it was included in Ptolemy's 48 constellations, and is counted among the 88 modern constellations.Its name is Latin for "greater dog" in contrast to Canis Minor, the "lesser dog"; both figures are commonly represented as following the constellation of Orion the hunter through the sky. The Canis Major Dwarf galaxy is located in the same part of the sky as the constellation of Canis Major. The Large Magellanic Cloud (LMC) is a dwarf irregular galaxy located on the border between the constellations Dorado and Mensa.
