Crux is located in the Southern Hemisphere and is best seen in May. Crux is the smallest official constellation; however, it is also one of the most distinctive constellations in the Southern Hemisphere. It contains Acrux, the thirteenth-brightest star in the night sky, and historically Crux was frequently used by sailors to determine the position of the south pole.
Crux is represented in the national flags of Australia, Brazil, New Zealand, Papua New Guinea, and Samoa.
There is no mythology associated with this constellation.
