Capricorn is the tenth astrological sign in the Zodiac, originating from the constellation of Capricornus. In western astrology, this sign is no longer aligned with the constellation as a result of the precession of the equinoxes. In astrology, Capricorn is considered a "feminine", negative sign. It is also considered an earth sign and is one of four cardinal signs. Capricorn is ruled by the planet Saturn. Being the tenth sign of the zodiac, Capricorn has been associated with the astrological 10th house.

Individuals born when the Sun was in this sign are considered Capricorn individuals. Under the tropical zodiac, the Sun is in Capricorn roughly from December 22 to January 19. Under the sidereal zodiac, it is currently there roughly from January 15 to February 12.
