The data suggests that the trail of stars is actually part of the warped galactic Thin disk and Thick disc population and not a result of the collision of the Milky Way with a dwarf spheroidal galaxy. [4] This conclusion, however, is still being challenged and the true nature of the overdensity in Canis Major remains unknown. The SensagentBox are offered by sensAgent.

[3] The stream of stars was first discovered in the early 21st century by astronomers conducting the Sloan Digital Sky Survey. In this interaction, the larger galaxy, designated NGC 2207, is pulling large amounts of gas and dust from its smaller companion, designated IC 2163, in a process that has initiated a high rate of star formation in both galaxies. The Canis Major Dwarf Galaxy (CMa Dwarf) is an irregular galaxy that is approximately elliptical in shape, and has the distinction of being the galaxy that is closest to our solar system, being only about 25 000 light years away. This galaxy contains a relatively high percentage of red giant stars, and it's estimated to have one billion stars in total. There are no meteor showers associated with the Canis Major constellation. Letters must be adjacent and longer words score better. However, since the main structure of the Canis Major Dwarf galaxy is severely degraded, most investigators believe that the globular clusters and the galaxy itself represent the remains of a larger, denser structure that was tidally disrupted by the Milky Way galaxy.
