- Canis Major (Wikipedia)
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 Milky Way passes through Canis Major and several open clusters lie within its borders, most notably M41.
