Canis Minor
The Orion Family, on the opposite side of the sky from the Hercules Family, includes Orion, Canis Major, Canis Minor, Lepus, and Monoceros. This group of constellations draws from Greek myth, representing the hunter (Orion) and his two dogs (Canis Major and Canis Minor) chasing the hare (Lepus). Menzel added the unicorn (Monoceros) for completeness.
