Pyxis (/ˈpɪksᵻs/; Greek:box) is a small and faint constellation in the southern sky. Abbreviated from Pyxis Nautica, its name is Latin for a mariner's compass (contrasting with Circinus, which represents a draftsman's compasses). Pyxis was introduced by Nicolas Louis de Lacaille in the 18th century, and is counted among the 88 modern constellations. The constellation is located close to those forming the old constellation of the ship Argo Navis, and in the 19th century astronomer John Herschel suggested renaming Pyxis to Malus, the mast, but the suggestion was not followed. Pyxis is completely visible from latitudes south of 53 degrees north, with its best evening-sky visibility in February and March.
