Cancer

The constellation Cancer is a crab. Look for Cancer from December through June. It's hard to see Cancer because the stars are so dim.

To find Cancer, first find Gemini and Leo. Cancer is right between them! Have you looked at the picture yet? Do you see a body with two claws coming out?

A story about Cancer is found in Greek mythology. Heracles was in a fight with the monster Hydra. A giant crab tried to help Hydra, but Heracles smashed it with his foot. The crab was so brave, that Hera put it in the sky. Can you find Cancer in the night sky?
