The constellation Circinus is a small constellation in the southern sky, first defined in the 18th century. Its name is Latin for compass, referring to the drafting tool used for drawing circles; it should not be confused with Pyxis, a constellation that represents a mariner's compass.

History

Circinus was introduced in the 18th century by Nicolas Louis de Lacaille, whose fascination with secular science led him to name the constellations he defined after scientific instruments.

Location

Circinus is located at a declination of −50 to −60 degrees, and hence the whole constellation is visible only south of the 30° north latitude.
