This is one of the 13 constellations of the Zodiac.
Aquarius is a rather faint constellation which would not be famous if it weren't part of the Zodiac. Aquarius, as its name suggests is universally associated with water. In most cultures, it is drawn as a man pouring water from a bucket. This may arise from the fact that the Sun enters Aquarius in early winter when the rainy season begins in many parts of the world.
