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.

( 2004a) as an excess in the density of Two Micron All Sky Survey (2MASS) M-giant stars in the direction ( l, b) = (240°, − 8°) compared to similar fields in the northern galactic hemisphere. Milky Way, the identification of the Canis Major dwarf galaxy (as this overdensity will now be referred to) rep-resents the first detection of an accretion occurring within the plane of the Galaxy. However, there remains debate over whether it represents a disrupted dwarf galaxy or in fact a variation in the thin and thick disk and spiral arm populations of the Milky Way. 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.

Astronomers can measure the distances to M giants fairly accurately because those of a given infrared color have nearly the same luminosity. 1. Based upon an annual parallax shift of 33.80 mas as seen from Earth, this system is located 96.5 light years from the Sun.The star is moving in the general direction of the Sun with a radial velocity of −37.9 km/s. The Canis Major Dwarf Galaxy is also known as the Canis Major Overdensity. The CMa overdensity is located towards the Galac-tic anti-centre direction at roughly 8 kpc from the sun [Bellazinni et al. In response to recent criticism by Momany et al., that the recently identified Canis Major (CMa) overdensity could be simply explained by the Galactic warp, we present proof of the existence of a stellar population in the direction of CMa that cannot be explained by known Galactic components. Canis Major Overdensity. Andromeda. The Canis Major Dwarf Galaxy ( CMa dwarf) or Canis Major Overdensity ( CMa overdensity) is a disputed dwarf irregular galaxy in the Local Group.

Svetlana Savitskaya. Canis is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals.Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails. The main aim is to unravel the complex mixture of stellar populations toward this Galactic direction, where in the recent past important signatures of an accretion event have been claimed Savitskaya. (2004) argued that the Canis Major overdensity could be explained by taking into account the stellar warp the Canis Major Overdensity.
