Cancer is represented in the heavens as a crab situated between Leo on the east and Gemini on the west. It is best viewed in the early spring near the celestial equator. Cancer is the faintest constellation in the entire zodiac, its brightest star is only of the fourth magnitude. M-44 or “the Bee Hive Cluster” can be seen with binoculars. It is bordered by the constellations Canis Minor, Gemini, Hydra, Leo, Leo Minor, and Lynx. 

Here are some famous people with stars named after them in the Cancer constellation: John Cusack, Princess Diana, and Ashley Tisdale. Click here for more information.

In the zodiacs of Esne and Dendera, and in most of the astrological remnants of ancient Egypt, a scarab or beetle symbolizes Cancer. In Sir William Jones’s Oriental Zodiac, and in some others found in India, we meet with the figure of a crab. As the Hindus probably derived their knowledge of the stars from the Chaldeans, it is supposed that the crab sign is more ancient than the beetle. The sign of Cancer usually is assigned to the tribe of Reuben in Jewish astrological lore. In some eastern representations of this sign, two animals which look like jack-asses are found. Because the Chaldaic name for the ass may be translated “muddiness,” it is supposed to allude to the discoloring of the Nile, since that river rose when the sun entered Cancer. In copying this sign, the Greeks also symbolized it with two jack-asses because these animals assisted Zeus in his victory over the giants. 

Mythological stories give different accounts of the origin of this constellation. The prevailing opinion is that while Hercules was engaged in his famous contest with the dreadful Hydra, Juno, envious of the fame of his achievements, sent a sea-crab to nip, bite and annoy the hero. Though the crab was soon crushed underfoot by Hercules, the goddess placed it among the constellations in reward for its services. Like other zodiac constellations, Cancer was catalogued by the Greek astronomer Ptolemy in the 2nd century.

Mythology of the Constellation Cancer 


In another legend, Cancer is associated with the second great feat of Hercules. In the story of the “Twelve Labours of Hercules”. Cancer the Crab was sent by Hera rather than Juno to fight alongside the sea monster Hydra. Hercules had been sent to vanquish the Lernaean Hydra who resided at the entrance to the underworld.   The monster Hydra had been raised by Hera for the purpose of slaying Hercules. The fearsome, multi-headed beast was so noxious that even the scent of it was deadly. To help defeat Hydra, Hercules enlisted the help of his nephew Iolaus to cauterize each head so it would not regenerate in the fight.  The goddess Hera was not pleased to see the pair overcoming murderous sea monster so as a distraction she also sent the giant crab who attacked the Hero. Hercules made short work of the crab and slayed both Hydra and Cancer. Heartbroken at the loss of the two, Hera put both Hydra and Cancer in the stars.
