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.
T Pyxidis is a nova remnant and recurrent nova in the constellation Pyxis. It is a binary star system. Because of their close proximity, the white dwarf continuously draws matter from the less massive star until it becomes unstable, causing another nova.
