Aquarius is the eleventh astrological sign in the Zodiac, originating from the constellation Aquarius. In astrology, Aquarius is considered a "masculine", positive (extrovert) sign. It is also considered an air sign and is one of four fixed signs. Aquarius is known for its preference in the unconventional, and its powerful intellect, considered to be a stroke of "creative genius". Aquarius has been traditionally ruled by the planet Saturn, and, since its discovery, Uranus has been considered a modern ruler of this sign. Being the eleventh sign of the zodiac, Aquarius is associated with the astrological eleventh house. Individuals born when the Sun was in this sign are considered Aquarius individuals. Under the tropical zodiac, the Sun is in Aquarius roughly from January 20 to February 19.
