Canis Major

The Greater Dog

Canis Major is a constellation in the southern celestial hemisphere. Its name is Latin for "greater dog."

The Greater Dog and its companion Canis Minor, the Lesser Dog are commonly represented as following the hunter Orion through the sky.

The constellation's main star Sirius ( α CMa) is the brightest star in the night sky and - at a distance of only 8.6 light years - one of Earth's nearest neighbors.

Sirius is also part of two asterisms, the Winter Triangle and the Winter Hexagon.

Canis Major is one of the 48 original Ptolemaic Constellations.
