The origin of cancer name

The name of Cancer is Cancer, which is related to the Greek goddess Hera. Hera is the sister of Zeus, the supreme ruler of heaven and earth in the era of Olympia gods. Zeus married Hercules, the son of Akmeni, an earthly girl, and Princess Derby, and lived a happy life.

But Zeus was enchanted by Hera, and Heracles killed his wife himself, and he wanted to commit suicide himself. In order to make him atone, Zeus was appointed king of Jeristos, and he had to go through twelve adventures to subdue the monster Sidorah who lived in the swamp.

Sedola is a giant snake with only nine heads, hiding in a cave near the swamp. Hercules threw a torch at it, and the enraged Sedola spat out poison gas. Cancer, who lives in the swamp, saw Sedola's painful struggle and jumped out to bite Hercules' foot. Therefore, cancer was shattered and Cedora was subdued. Hera set up cancer in the sky because she was sad about its death.

Cancer is one of the zodiac signs, with an area of 505.87 square degrees, accounting for 1.226% of the whole day. There are 23 stars in Cancer that are brighter than 5.5, and the brightest star is Akira Masugo (Cancer β).
