Saturn is the last planet visible to the naked eye. For millennia, it represented the limits of the solar system and came to symbolize time, structure and order. Saturn takes about 29 years to orbit the Sun, spending about two and a half years in each sign of the zodiac.

Saturn is the planet that says "no" but means "yes." The no comes from Saturn showing us what isn't working, sometimes in the form of frustrating blockages or delays. But these help us see where we need to put in effort to make concrete changes. Saturn says "yes" as the planet of crystallization that brings energy into matter. Saturn's presence in a sign of the zodiac shows us where we are likely to meet limits and how to construct something useful.

Saturn is exalted in Libra, a traditional measure of this responsible planet's strength in this fair-minded sign. Although Saturn is about reality and airy Libra with ideals, a common sense of justice makes this a formidable combination. The necessity to consider others' points of view, to negotiate and meet them halfway is expected now. Relationships have to be put back into balance if they are to remain viable. Maturity, discipline and commitment allow partnerships to flourish while an irresponsible approach to alliances can prove costly.

Saturn in Libra is a time to engage with opposites by challenging ourselves to maintain civil discourse with our adversaries. This is about building bridges by recognizing that there are at least two sides to every story. It's not necessary that we find agreement on every point, or even the most essential ones. This is, however, a period when we all benefit by keeping lines of communication open, being honest and kind, and treating one another as equals.

Among the many famous people born with Saturn in Libra are Leonardo da Vinci, Edmond Halley, Genghis Khan, Jane Austin, Oliver Cromwell, Alexis de Tocqueville, Alfred Nobel, Henry Ford, Jean Renoir, J.B.
