What Each Planet Means in Astrology
From the Sun to Saturn, and Rahu and Ketu: what every planet represents in your birth chart and the part of life it governs.
In astrology, each planet stands for a different part of you. The sign a planet sits in shows how it behaves, and the house it sits in shows where in life it acts. Start with what each planet means and the rest of the chart becomes much easier to read.
The personal planets
These move quickly and describe your everyday character.
- Sun: identity, vitality, confidence and purpose. In Vedic astrology it also represents the father and authority.
- Moon: emotions, instincts, memory and the need for security. It also represents the mother and the mind.
- Mercury: thinking, speech, learning, trade and humour.
- Venus: love, beauty, pleasure, art and what you value.
- Mars: energy, courage, ambition, anger and the will to act.
The social planets
- Jupiter: growth, wisdom, teachers, faith and good fortune. It expands whatever it touches.
- Saturn: discipline, duty, patience, limits and the rewards of long effort. Saturn is slow, but what it builds lasts.
The lunar nodes: Rahu and Ketu
Rahu and Ketu are not physical planets. They are the two points where the Moon’s path crosses the Sun’s path, and eclipses happen near them. They are central to Vedic astrology.
- Rahu (north node): desire, ambition, obsession and the unfamiliar territory you are drawn towards.
- Ketu (south node): detachment, intuition, past skills and spiritual release.
The outer planets
Used mainly in Western astrology, these move so slowly that they mark whole generations.
- Uranus: change, freedom, invention and sudden breaks from the past.
- Neptune: dreams, imagination, compassion and illusion.
- Pluto: power, endings, renewal and deep transformation.
Quick reference
| Planet | Sanskrit name | Governs | Time in one sign |
|---|---|---|---|
| Sun | Surya | Self and purpose | About 1 month |
| Moon | Chandra | Mind and emotions | About 2.5 days |
| Mercury | Budha | Communication | About 3 to 4 weeks |
| Venus | Shukra | Love and comfort | About 4 weeks |
| Mars | Mangal | Energy and courage | About 6 to 7 weeks |
| Jupiter | Guru | Wisdom and growth | About 1 year |
| Saturn | Shani | Discipline and karma | About 2.5 years |
| Rahu and Ketu | Rahu, Ketu | Desire and release | About 18 months |
The times are averages. When a planet turns retrograde it can stay in one sign for much longer.
Putting it together
No planet is simply good or bad. Saturn brings pressure but also maturity. Jupiter brings luck but also excess. A reading looks at how strong each planet is in your chart and how they work together, which is why two people with the same Sun sign can have such different lives.
