In astrology, Saturn is associated with restriction and limitation. Where Jupiter expands, Saturn constricts. Although the themes of Saturn seem depressing, Saturn brings structure and meaning to our world. Saturn knows the limits of time and matter. Saturn reminds us of our boundaries, our responsibilities, and our commitments.

Saturn is the planetary ruler of Capricorn, a sign known as ambitious, hard-working and persistent. It is an earth sign, which means it is focused on the here and know and getting the most out of every opportunity. Before the discovery of Uranus, Saturn also ruled the zodiac sign Aquarius.
