How Did the Sagitta Constellation Get Its Name?


Sagitta is a small constellation in the northern hemisphere that is often overlooked due to its dimness. Despite its size, it has a rich history and mythology. But how did this constellation come to be named Sagitta?

The Mythological Origin of Sagitta

In ancient Greek mythology, Sagitta was known as the arrow of Hercules. According to the myth, Hercules was tasked with defeating the Stymphalian birds, which had steel feathers and were terrorizing the countryside. Hercules used his bow and arrow to kill the birds, and as he did so, one of his arrows missed its target and flew into the sky, becoming the constellation we now know as Sagitta.

Sagitta should not be confused with its neighbor the Sagittarius constellation. Sagittarius is the archer whereas Sagitta is the arrow.

The Historical Significance of Sagitta

Sagitta was first cataloged by the Greek astronomer Ptolemy in the 2nd century AD. It has been known by several names throughout history, including “Sagitta” in Latin, which means “arrow,” and “Sagitta Kwei,” in Chinese, which means “the arrow.”

Sagitta played an important role in navigation during the Age of Discovery, as sailors used it to find their way across the oceans. It was one of the constellations included in the first scientific star atlas, “Uranometria,” published in 1603 by Johann Bayer.

Observing Sagitta

Sagitta is a small constellation that is located between the constellations of Aquila and Vulpecula. It is not particularly bright, with no stars brighter than fourth magnitude, making it difficult to see in light-polluted areas. The best time to observe Sagitta is during the summer months when it is highest in the sky.


The Sagitta constellation has a rich history and mythology, with its name originating from the arrow of Hercules in ancient Greek mythology. It played an important role in navigation during the Age of Discovery and has been known by various names throughout history. Despite its dimness, it remains an intriguing constellation for stargazers and astronomers alike.
