Cancer is the fourth astrological sign in the Zodiac, originating from the constellation of Cancer. In western astrology, this sign is no longer aligned with the constellation as a result of the precession of the equinoxes. In astrology, Cancer is considered a yin sign or alternatively feminine or negative sign, meaning it is more introverted. It is considered a water sign, and is one of four cardinal signs. Cancer is ruled by the Moon. Being the fourth sign in the zodiac, Cancer has been associated with the astrological 4th house. Individuals born when the Sun was in this sign are considered Cancer individuals. Under the tropical zodiac, the Sun is in Cancer roughly from June 22 to July 22 and under the sidereal zodiac, it is currently roughly from July 16 to August 15.
