In Vedic astrology the planets, called grahas, are the working parts of every chart. There are nine of them, and each one stands for a particular set of themes in life. This lesson introduces all nine grahas, explains why two of them are unusual, shows how each planet acts as a karaka or significator, and clears up the common mix-up between planets and stars. Once you know what each graha represents, the rest of the course becomes far easier to follow.
The Nine Grahas
Vedic astrology works with nine grahas: the Sun (Surya), the Moon (Chandra), Mars (Mangal), Mercury (Budha), Jupiter (Guru or Brihaspati), Venus (Shukra), Saturn (Shani), and the two lunar nodes, Rahu and Ketu.
The word graha comes from a Sanskrit root meaning to grasp or seize, which fits the way each planet is said to take hold of a part of life and colour it. Notice that this list does not include Uranus, Neptune, or Pluto. The classical system was built around the seven visible bodies plus the two nodes, and traditional Vedic practice still reads charts with these nine alone.
Rahu and Ketu: The Shadow Points
Rahu and Ketu are different from the other seven. They are not physical planets you could point a telescope at. They are the two points where the Moon's path around the Earth crosses the Sun's apparent path, known as the lunar nodes. Because they have no body, they are called shadow planets, or chhaya grahas.
Rahu is the north node and Ketu the south node, and they always sit exactly opposite each other in the chart. Eclipses happen when the Sun and Moon line up near these points, which is why old texts describe Rahu and Ketu as the parts of a mythical serpent that swallows the Sun and Moon. In a reading, Rahu is linked to worldly desire, ambition, and obsession, while Ketu points to detachment, loss, and spiritual liberation.
Every Planet Is a Karaka
A central idea in Jyotish is that each graha is a karaka, meaning a significator or natural indicator of certain matters. The planet carries those themes wherever it goes in the chart.
For example, the Sun is the karaka for the soul, the father, and authority. The Moon signifies the mind, emotions, and the mother. Jupiter is the karaka for wisdom, children, and wealth, while Venus stands for love, marriage, and comfort. Mars carries energy, courage, and siblings; Mercury rules speech, intellect, and trade; Saturn governs discipline, delay, and longevity. Learning these natural significations is one of the most useful things a beginner can do, because they apply in every chart.
Planets Are Not the Same as Stars
Beginners often blur planets and stars together, but they are very different in astrology. A planet moves across the sky against a fixed backdrop, changing signs over days, months, or years. The grahas are the moving pieces an astrologer tracks.
The stars form the unchanging background. In Vedic astrology this backdrop is divided into the twelve zodiac signs and into twenty-seven nakshatras, the lunar mansions. Stars set the stage; planets are the actors who move across it. When someone says a planet is in a certain sign or nakshatra, they mean the moving graha is currently positioned against that fixed stellar region.
A Quick Tour of Each Planet
Here is the shortest useful summary of all nine. The Sun rules identity, vitality, and the father. The Moon governs the emotional mind and the mother. Mars brings drive, anger, and physical courage. Mercury handles thinking, communication, and commerce.
Jupiter, the great benefic, expands whatever it touches and signifies teachers, faith, and growth. Venus brings pleasure, art, and relationships. Saturn, the strict teacher, rules time, hard work, and the consequences of our actions. Rahu inflates ambition and craving, and Ketu strips things back toward detachment. Keep these in mind and you will recognise the same themes appearing again and again.
Key takeaways
- Vedic astrology uses nine grahas: Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, and Ketu.
- Rahu and Ketu are not physical planets but the two lunar nodes, the points where the Moon's path crosses the Sun's path, so they are called shadow planets.
- Each graha is a karaka, a natural significator of specific themes such as the Sun for soul and father, or the Moon for mind and mother.
- Planets are the moving bodies an astrologer tracks; stars and nakshatras form the fixed backdrop they move across.
- Knowing what each planet naturally signifies is the foundation for reading any chart.
