Canis Major is a constellation that is in the southern sky. It means "greater dog" in Latin (also called large dog). There is also the constellation Canis Minor, which means "lesser dog" in Latin. The astronomer named Ptolemy listed Canis Major when he made a list of 48 constellations. It is also one of the 88 modern constellations that were made by the International Astronomical Union.
