Canis Minor is one of Orion's hunting dogs. It trots along behind its master unperturbed by the unicorn (Monoceros), and leaving the hare (Lepus) to the greater dog (Canis Major) to chase. It's a small constellation with not much more to offer than one bright star, but it has a long history.

The constellation Canis Minor can be seen alongside Monoceros the Unicorn and the obsolete constellation Atelier Typographique (Printing Office) in this 1825 star chart from Sidney Hall's Urania's Mirror.

View from the dark night sky above La Palma in the Canary Islands. The picture was made by a group of experienced astrophotographers who traveled there to take advantage of the ideal observing conditions near the Observatorio del Roque de los Muchachos.

Faint stars along the plane of our Galaxy compose the delicate, luminous band of the Milky Way stretching across the image from the bottom left. Orion the hunter is easy to find, with glowing nebulae highlighting the hunter's belt and sword. Orion's famous red giant star Betelgeuse, near picture center, has a yellowish cast and Rigel is the bright star in Orion at lower right. Brilliant white Sirius, near the bottom, is the brightest star in the picture (and in Earth's night sky). Sirius is part of the constellation Canis Major. Across the Milky Way, above and to the left of Sirius, is slightly less brilliant Procyon, brightest star of Canis Minor. A V-shaped group of yellowish stars at the upper right, part of Taurus the bull, is dominated by the red giant Aldebaran.

If you saw the movie Cold Mountain, you'll have seen this North Carolina sky. And it will be familiar to many northern hemisphere viewers.

You can pick out Orion by finding the three stars of his belt. Follow the line of the belt stars down to a bright star - that's Sirius (the dog star) in Canis Major. Above and to the right of the belt is the blue star Bellatrix. To the left of Bellatrix is the red supergiant Betelgeuse.

Sirius and Betelgeuse are two stars of the Winter Triangle. Can you spot the third one, Procyon? It's the brightest star of Canis Minor. You can only see two stars of Canis Minor in this photo. It's a small and generally dim constellation.
