Aquarius is a large constellation in the Southern Hemisphere that can be seen during October. Aquarius is located in a section of the sky that is occasionally referred to as the "water" section, due to the other water-related constellations in the area: Cetus, Delphinus, Eridanus, Pisces, and Piscis Austrinus.

Aquarius is the radiant point of the Eta Aquarids meteor shower. It typically begins around April 16 and ends around May 28, peaking from May 6-7. The Eta Aquarids are named after the star Eta Aquarii and are created by the passage of Halley's Comet.

In astrology, Aquarius is the eleventh sign of the Zodiac.


In Greek mythology, Aquarius represents Ganymede, the cup bearer of the gods. Zeus saw Ganymede tending to a flock of sheep and decided he wanted the boy serving him on Mount Olympus, so he sent an eagle down to Earth to kidnap Ganymede and bring him to Olympus.
