The story behind the name: Circinus was created by de Lacaille during his stay at the Cape of Good Hope in the mid-18th century. Circinus is a very small and faint constellation. The three brightest stars form a narrow triangle. The shape is reminiscent of a drawing (or drafting) compass of the sort used to plot sea and sky charts.
