Pyxis constellation lies in the southern sky. It represents a mariner’s compass. It was one of the constellations created by the French astronomer Nicolas Louis de Lacaille in the 18th century. Lacaille originally named the constellation Pyxis Nautica, but the name was later simplified to just Pyxis.
