Sagitta is a small constellation in the northern sky. Its name is Latin for 'arrow'. It is one of the 48 constellations listed by Ptolemy and one of the 88 modern constellations defined by the International Astronomical Union (IAU).

Sagitta was called Oistos 'the arrow' by the ancient Greeks,[1] and it was one of the 48 constellations listed by Ptolemy.[2] Richard Hinckley Allen proposed that Sagitta could represent the arrow shot by Hercules towards the Stymphalian birds.[3]
