Canis Minor is one of the 88 modern constellations and was also in Ptolemy's list of 48 constellations.
Location: Northern Winter 8h RA 5° Dec
Its name is Latin for "lesser dog", in contrast to Canis Major, the "greater dog"; both figures are commonly represented as following the constellation of Orion the hunter.
Canis Minor is a small constellation mainly consisting of two stars. Procyon is the eighth brightest star in the night sky. Procyon means 'anterior dog' in Greek, as it rises before the Dog Star, Sirius, of Canis Major.
Canis Minor Mythology
Canis Minor was considered to be the smaller of the two hunting dogs of Orion. However, the ancient Greeks did not recognize it as a distinct constellation, and thus originally only considered Orion to have had one dog.
Canis Minor Deep Space Objects
