How did the Canis Minor constellation get its name?


The Canis Minor constellation is one of the 88 modern constellations and is located in the southern sky. It is one of the smallest constellations, but it has a rich history and mythology. In this article, we’ll explore how this constellation got its name and the stories behind it.

History of the Canis Minor Constellation

The Canis Minor constellation has been known since ancient times and was first cataloged by the Greek astronomer Ptolemy in the 2nd century CE. The stars of the Canis Minor constellation were believed to represent a dog and its name comes from the Latin words for “lesser dog.”

Mythology Behind the Canis Minor Constellation

In Greek mythology, the Canis Minor constellation is associated with the story of the huntress goddess Artemis and her loyal dog, Laelaps. According to the myth, Artemis gave Laelaps to Procris, the wife of Cephalus, as a gift. Procris used Laelaps to hunt the Teumessian fox, a giant beast that could never be caught. As Laelaps chased the fox, Zeus, the king of the gods, was so impressed with their speed that he turned both Laelaps and the Teumessian fox into constellations. Laelaps became the Canis Minor constellation, and the Teumessian fox became the Canes Venatici constellation.

Another myth associates the Canis Minor constellation with the Greek god Dionysus and his companion, a small dog named Maera. Maera was known for being fiercely loyal to Dionysus and is often depicted with him in artwork. When Maera died, Dionysus placed him in the sky as a constellation, which became the Canis Minor constellation.


The Canis Minor constellation has a rich history and mythology that dates back to ancient times. Its name comes from the Latin words for “lesser dog,” and it is associated with the Greek myths of Artemis and Laelaps and Dionysus and Maera. Despite its small size, the Canis Minor constellation remains an important part of astronomy and continues to fascinate stargazers and astronomers alike.
