At left is an illustration of the Milky Way, the Canis Major Dwarf, and the stream of material coming from the Galaxy. A little farther away at 123 light years and still beyond naked eye visibility at magnitude 7.63 is HD 47186, a G6V yellow main sequence star, very like our Sun, which also has two known planets. Omicron(2) Canis Majoris has the Arabic name Thanih al Adzari, second of the virgins. VY Canis Majoris is so large that if our Sun were replaced by it, its surface would extend to (or maybe even pass) the orbit of Saturn.In Earth terms it would take 70 000 000 000 000 000 (70 quadrillion) Earths to fill up the VY Canis Majoris. The bright central star is Tau Canis Majoris, and the grouping is often referred to as the Tau Canis Majoris Cluster. Canis Major Dwarf Galaxy is a dwarf galaxy deep space object. The gravitational pull of our galaxy is so high that both Sagittarius Elliptical and Canis Major dwarfs are being absorbed into the Milk Wayâa process, however, will complete within a billion years or so. 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. It is a B4I blue supergiant, so luminous that even at the very great distance of 2,800 light years, it's still bright enough to shine in our sky with a magnitude of 3.04. Open star cluster NGC 2362 is also visible to the naked eye at magnitude 4.1. 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.. As the name suggests, a dwarf galaxy is a small galaxy made up of a billion stars. The galaxy, which is also known as Messier 51a, is interacting with NGC 5195 (Messier 51b), a dwarf galaxy, also in Canes Venatici. The Canis Major Galaxy is the nearest dwarf galaxy to 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. The constellation of Canis Major contains several interesting deep-sky objects as well, such as the Canis Major Dwarf Galaxy, the emission nebula NGC 2359 – also known as Thor’s Helmet, or the colliding spiral galaxies NGC 2207 and IC 2163. 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. Beta Canis Majoris is named Murzim, Arabic for the announcer, as it precedes Sirius across the sky, heralding the appearance of the great dog star. The name Sirius is Greek for scorching. This star is quite an average star, however is so bright in the sky as its so close to us.

The Canis Majoris Dwarf Galaxy is an irregular-shaped galaxy, as it is currently in the process of being ripped apart by the gravitational force of the Milky Way Galaxy. What is a Neutron Star? Pisces Dwarf (unclear if it is a satellite of the Andromeda Galaxy or the Triangulum Galaxy) Other Galaxies in the Local Group There some "oddball" galaxies in the Local Group that may not be gravitationally "bound" to either the Andromeda or the Milky Way galaxies. Farther still at 75 million light-years is NGC 2280, a spiral galaxy with a magnitude of 11.0. In ancient times it was thought the energy of Sirius combined with the Sun at this time, and the star was blamed, in the words of Robert Burnham Jr., for "bringing forth fever in men and madness in dogs.". A closeup of the central region of NGC 2359 reveals the giant Wolf Rayet star HD 56925, very bright in the left centre of the image below. It is one of the largest open clusters, estimated to contain about 500 stars, about 4,000 light years away. It is the closest known galaxy to the Milky Way; the second most closest is the Sagittarius Dwarf Elliptical galaxy. The galaxy contains a relatively high percentage of red giant stars, and is thought to contain an estimated one billion stars in all.. It is a B1III blue giant, 450 light years away. 2. a galaxy that has no elliptical or spiral shape, and hence it does not come under the Hubble Sequence of regular galaxy classes.

Famed British astronomer Ian Ridpath conducted an excellent in depth study of Temple's theories called Investigating The Sirius Mystery. Astronomers are of the opinion that the Canis Major dwarf galaxy may have been brought together with different globular clusters, including NGC 2298 and NGC 1851. It is the closest known planetary system in Canis Major, about 65 light years away. Canis Major Dwarf Galaxy Location. History: The Canis Major Dwarf Galaxy was discovered by a team of British, Australian, French, Italian astronomers in November 2003. NGC 2359 is an emission nebula, given the name Thor's Helmet. Canis Minor was at first cataloged by the Greco-Roman astronomer Ptolemy, as an asterism, in his 2 nd century Almagest, that was comprised out of 48 constellations. 3. Interesting Andromeda Galaxy Facts: 11-20. The Canis Major Dwarf Galaxy, which was discovered in 2003, is the Milky Way's nearest neighbor. Whirlpool Galaxy – Messier 51 (NGC 5194) The Whirlpool Galaxy is one of the best known galaxies in the night sky. Eta Canis Majoris is Aludra, Arabic for the virgin. The problem is that it should normally take at least 100,000 years for a red giant to become a white dwarf, so the colour discrepancy remains a mystery. Some suggest that colours were sometimes interpreted differently in ancient times. Because gas and dust cannot block infrared, it becomes easier for astronomers to detect galaxies hidden in dense concentration of stars, dust and gases. In 2003, the Canis Major Dwarf Galaxy was discovered - this is now the closest known galaxy to ours! The galaxy is over 190 million years old. For a star to be listed in this designation, their diameter must measure to be at least 3,600 times larger than the diameter of the Sun. Hypergiants, like VY Canis Majoris are the most luminous stars in the galaxy, with only 10 currently placed in the Milky Way galaxy. It has recently been settled by the Solarian Kingdom. It is a spectroscopic binary, 360 light years away. Since Sirius B is far beyond naked eye visibility, the book suggests this knowledge was imparted to the Dogon when they were visited by aliens who lived in the Sirius star system. 4. Classified as a K1III yellow/orange giant, it has a gas giant planet in orbit around it 2.6 times the size of Jupiter. Because Sirius is so bright, when it is close to the horizon, it puts on quite a show, atmospheric refraction turning it into a wild kaleidoscope of dazzling, sparkling colors.
