Sea (astronomy)

From Wikipedia, the free encyclopedia

The Sea or the Water is an area of the sky in which many water-related, and few land-related, constellations occur.

Most of these constellations are named by Ptolemy:

• Aquarius the Water-bearer
• Capricornus the Sea-goat
• Cetus the Whale
• Delphinus the Dolphin
• Eridanus the Great River
• Hydra the Water serpent
• Pisces the Fishes
• Piscis Austrinus, the Southern Fish (not named by Ptolemy)

Sometimes included are the Argo Ship and Crater the Water Cup.

Some water-themed constellations are newer, so are not in this region. They include Hydrus, the lesser water snake; Volans, the flying fish; and Dorado, the swordfish.
