The Tenth House is the top of the chart, the highest point, the Midheaven. It is the house of career, reputation, and public standing. It describes your professional life, your public image, and the legacy you leave behind. It is the house of achievement, of ambition, of the long climb to the top.
In traditional astrology, the Tenth House is called the House of Kings (or Profession). It describes your relationship with authority figures, your public reputation, and the profession by which you make your mark on the world.
A planet in the Tenth House describes how you pursue career and public standing. Saturn in the Tenth House is at home, giving a serious, disciplined approach to career, and often achievement through slow, steady effort. The Sun in the Tenth House gives a strong drive for recognition and public achievement. Jupiter in the Tenth House often brings good fortune in career matters, and a reputation for generosity and integrity.
The Tenth House is naturally associated with Capricorn and Saturn: the sign of ambition and the planet of structure. When planets are placed in the Tenth House, they take on something of this Capricornian quality, becoming more ambitious, more disciplined, more focused on achievement.
