With an area of 93 square degrees, the Compasses (lat. Circinus) is the fourth smallest constellation in the sky. Since only one of its stars reaches the third magnitude, it is relatively unremarkable.
After the invention of the telescope, the French astronomerNicolas de Lacaillenamed some constellations of the southern hemisphere that had not been recognized before. Unlike the 48 constellations of antiquity, which bear the names of mythological figures, he often used the name of technological novelties for the new constellations.
