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 "feminine", negative (introvert) sign. It is also 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 fourth house. Individuals born when the Sun was in this sign are considered Cancer individuals. Under the tropical zodiac, the Sun enters Cancer on the moment of summer solstice by definition, or roughly on June 22, leaving it around July 23. Under the sidereal zodiac, it is currently roughly from July 16 to August 15. The Sanskrit name of Cancer in Hindu astrology is Karka.
