Cancer

The Crab

Cancer is small and dim, and to many it does not resemble a crab. It lies between Gemini to the west and Leo to the east, Lynx to the north and Canis Minor and Hydra to the south.

Constellation Guide Cancer

Cancer is best noted among stargazers as the home of Praesepe (M44), an open cluster also called the Beehive Cluster or the Gate of Men, which contains the star η Cancri.

Cancer Mythology

Cancer, the Crab, plays a minor role in the Twelve Labors of Hercules. While Hercules was busy fighting the multi-headed monster, Hydra, the goddess Hera, who did not like Hercules, sent the Crab to distract him. Cancer grabbed onto the hero's toe with its claws, but barely breaking the rhythm of his great battle with Hydra, Hercules crushed the crab with his foot. Hera, grateful for the little crustacean's heroic but pitiful effort, gave it a place in the sky.

Notable Objects in Cancer

Cancer is best known among stargazers as the home of Praesepe (Messier 44), an open cluster also called the Beehive Cluster.

The smaller, denser open cluster Messier 67 can also be found in Cancer, 2600 light-years from Earth.
