There are 88 known constellations, some of which are Orion, Ursa Major, Ursa Minor, and Centaur. While the Big Dipper and Little Dipper appear to be constellations, they are actually part of the larger Ursa Major and Ursa Minor constellations. Various myths are associated with these constellations, such as Orion's death leading to his placement in the sky, Chiron's wounding and subsequent honor as the Centaur constellation, and Callisto and her son's transformation into the Ursa Major and Ursa Minor after angering Zeus.
