Sea (astronomy)

The Sea or the Water is an area of the sky in which many water-related, and few land-related, constellations occur. This may be because the Sun passed through this part of the sky during the rainy season.

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 ship Argo 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.
