Capricorn is the tenth sign of the zodiac, the sign of the winter solstice, and the sign of ambition, structure, and the long climb to the top. After the expansive optimism of Sagittarius, Capricorn turns to the hard work of building something that lasts.
Element: Earth — practical, grounded, and concerned with the material world. Mode: Cardinal — initiating, moving, and seeking to create change. Ruler: Saturn, the planet of structure and discipline.
Capricorn energy is disciplined, ambitious, and deeply practical. It sees what needs to be done, makes a plan, and executes it step by step, no matter how long it takes. It is patient, responsible, and capable of extraordinary endurance. But it can also be cold, pessimistic, and so focused on the goal that it forgets to enjoy the journey.
In the body, Capricorn rules the bones, the knees, and the teeth. In traditional astrology, it is associated with rulers, administrators, elders, and anyone who bears responsibility for others.
When a planet is placed in Capricorn, it takes on something of this quality. Mars in Capricorn is exalted, fighting with strategic endurance, pursuing its goals with disciplined persistence. The Moon in Capricorn is in its detriment, finding emotional security in achievement, struggling to express feelings openly. Jupiter in Capricorn is in its fall, expanding through discipline, learning the lesson that growth must be earned through sustained effort.
