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. U.G. Several studies cast doubts on the true nature of this overdensity. The distance to the centre is over 25,000 Lieutenant Yrs whereas Canis Major is 25,000 Lieutenant Yrs. This paper summarises the recent discovery of another potential Milky Way accretion event, the Canis Major dwarf galaxy. Key Facts & Summary. – Source. Galaxy- A huge collection of stars gas and dust . The Canis Major Dwarf Galaxy's location is 07h 12m 35.0 (R.A.) and -27d 40' 0 (Dec.). There are 1 billion stars in the canis galaxy. The type of galaxy is irregular. We have measured the absolute proper motion of the candidate Canis Major dwarf galaxy (CMa), at (l, b) =(240°, -8°).Likely main-sequence stars in CMa have been selected from a region in the color-magnitude diagram that has very little contamination from known Milky Way components. 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. has done some calculations as to how long it will take going at differing speeds. Spiral Galaxy- The stars and Gas clouds are concentrated mainly in one or Known as UGC 4459, this dwarf galaxy is located about 11 million light-years away in the constellation of Ursa Major. The Canis Majoris Dwarf Galaxy is about 42,000 light-years from the Milky Way’s Galactic Core. The Milky Way Galaxy is estimated to be about 10,000 times more massive than the Sagittarius Galaxy. It is in the same part of the sky as the constellation Canis Major. There are no meteor showers associated with the Canis Major constellation. There's no register feature and no need to give an email address if you don't need to. 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. A negative value indicates it is in the southern hemisphere. It is located 4 degrees South of Sirius and contains about 100 stars. The Canis Major Dwarf galaxy is so called because its small. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days). References: Nicolas F. Martin, Rodrigo A. Ibata, Michele Bellazzini, Michael J. Irwin, Geraint F. Lewis and Walter Dehnen, 2003. 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. The distance to the Canis Major Dwarf Galaxy is shorter than the distance to Sagittarius A*, the centre of the Milky Way. 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. Canis Major Dwarf: A New Closest Galaxy. The Right Ascension is the angular distance of an object along the celestial equator from the March Equinox. This dwarf satellite galaxy is found to lie just below the Galactic plane and appears to be on an equatorial orbit.

The galaxy is over 190 million years old. It has a roughly elliptical shape and is thought to contain as many stars as the Sagittarius dwarf elliptical galaxy, the previous contender for closest galaxy to us.

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 Canis Major Dwarf is an irregular dwarf galaxy that is a satellite of our own Milky Way Galaxy.It lies in the constellation Canis Major at a distance of only 25,000 light-years from the Sun and 42,000 light-years from the center of the Milky Way. The Large and Small Magellanic clouds were thought to be the closest galaxies to ours, until 1994, when the Sagittarius Dwarf Elliptical Galaxy (SagDEG) was discovered. ; Canis Minor would later be included in the 88 modern constellations, where it holds the 71 st place in regards to size, stretching for around 183 square degrees.
