The Nine Planets of Vedic Astrology

Vedic astrology works with 9 planets (Navagraha — Sanskrit: nine + graha, "seizer" or "influence"). These are: the Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, and the two lunar nodes Rahu and Ketu. Western astrology includes Uranus, Neptune, and Pluto; classical Jyotish does not use these as primary significators, though some modern Jyotishis incorporate them.

Each Graha is associated with a Nakshatra ruler (and therefore a Vimshottari Dasha period), zodiac sign rulerships, natural significations, and a set of life domains it influences in any chart.

Sun — Surya ☀️

Mahadasha: 6 years | Rules: Leo | Exalted in: Aries | Debilitated in: Libra

The Sun represents soul, authority, father, ego, vitality, government, and public recognition. It is the primary significator of the 1st house (self) and 10th house (career). A strong Sun gives leadership, confidence, and clear identity. The Sun Mahadasha of 6 years typically brings increased authority, career recognition, and a clearer definition of personal purpose.

Moon — Chandra 🌙

Mahadasha: 10 years | Rules: Cancer | Exalted in: Taurus | Debilitated in: Scorpio

The Moon represents mind, emotions, mother, public life, nourishment, and the subconscious. It is the most personally significant planet in Vedic astrology — your Janma Nakshatra, Rashi (Moon sign), and entire Dasha cycle are derived from the Moon's position. The Moon Mahadasha of 10 years tends to be emotionally rich, publicly active, and deeply connected to nurturing and relating.

Mars — Mangal ♂️

Mahadasha: 7 years | Rules: Aries, Scorpio | Exalted in: Capricorn | Debilitated in: Cancer

Mars represents energy, courage, ambition, siblings, property, and conflict. It is the planet of action and drive. A well-placed Mars gives determination, physical vitality, and the ability to execute. Mangal Dosha (the "Mars affliction") arises when Mars occupies certain houses, and is a factor considered in marriage compatibility. The Mars Mahadasha of 7 years is typically action-oriented and property-related.

Mercury — Budha ☿

Mahadasha: 17 years | Rules: Gemini, Virgo | Exalted in: Virgo | Debilitated in: Pisces

Mercury represents intellect, communication, business, skills, writing, siblings, and the analytical mind. It is the most intellectual planet and governs all forms of skilled work and commerce. The Mercury Mahadasha of 17 years is typically a period of intellectual development, communication-based career success, and the flowering of skills.

Jupiter — Guru/Brihaspati ♃

Mahadasha: 16 years | Rules: Sagittarius, Pisces | Exalted in: Cancer | Debilitated in: Capricorn

Jupiter is the great benefic of the Navagraha — the planet of wisdom, expansion, spirituality, teachers, children, and dharma. It is the significator of the 9th house (dharma, teacher, luck) and 5th house (children, creativity). Jupiter Mahadasha of 16 years is widely considered the most auspicious Dasha, bringing growth, opportunity, and spiritual development.

Venus — Shukra ♀️

Mahadasha: 20 years | Rules: Taurus, Libra | Exalted in: Pisces | Debilitated in: Virgo

Venus represents love, beauty, pleasure, relationships, wealth, and the arts. It is the second great benefic and the significator of marriage (especially in male charts), creativity, and material comfort. The Venus Mahadasha of 20 years — the longest in the Vimshottari system — is typically the most materially abundant and relationally significant period of life.

Saturn — Shani ♄

Mahadasha: 19 years | Rules: Capricorn, Aquarius | Exalted in: Libra | Debilitated in: Aries

Saturn represents discipline, karma, service, hard work, delays, endurance, and the lower classes. It is both a natural malefic and a planet that, when well-placed, produces lasting, structural success through patient effort. The Saturn Mahadasha of 19 years is typically a period of sustained effort, karmic accountability, and the slow construction of enduring achievements.

Rahu — North Lunar Node ☊

Mahadasha: 18 years | Rules: No sign (co-ruler of Aquarius in some traditions)

Rahu is the North Lunar Node — a mathematical point, not a physical body. It represents worldly desire, obsession, foreigners, technology, unconventional paths, and the karmic pull toward the future. Rahu amplifies and destabilises wherever it sits. The Rahu Mahadasha of 18 years is often a period of intense worldly ambition and significant life transformation.

Ketu — South Lunar Node ☋

Mahadasha: 7 years | Rules: No sign (co-ruler of Scorpio in some traditions)

Ketu is the South Lunar Node — always exactly opposite Rahu. It represents spiritual liberation, past-life karma, renunciation, sudden separations, and the capacity for moksha (liberation). Where Rahu pulls toward the world, Ketu pulls away from it. The Ketu Mahadasha of 7 years is often a spiritually intense period of letting go, simplification, and karmic completion.

Frequently Asked Questions

What are the Navagraha?

The Navagraha (Sanskrit: नवग्रह — nine planets) are the 9 celestial bodies used in Vedic astrology: Sun (Surya), Moon (Chandra), Mars (Mangal), Mercury (Budha), Jupiter (Guru/Brihaspati), Venus (Shukra), Saturn (Shani), Rahu (North Lunar Node), and Ketu (South Lunar Node). Unlike Western astrology, Vedic does not use Uranus, Neptune, or Pluto as primary significators.

What are Rahu and Ketu?

Rahu and Ketu are the lunar nodes — the two points where the Moon's orbit intersects the ecliptic (the Sun's apparent path). They are always exactly opposite each other in the chart (180° apart). Unlike the other 7 planets, they have no physical body; they are mathematical points. Rahu is associated with worldly desire and karmic pull toward the future; Ketu with spiritual liberation and past-life karma.

Which planet rules which zodiac sign?

Sun rules Leo. Moon rules Cancer. Mars rules Aries and Scorpio. Mercury rules Gemini and Virgo. Jupiter rules Sagittarius and Pisces. Venus rules Taurus and Libra. Saturn rules Capricorn and Aquarius. Rahu and Ketu do not rule signs but are co-rulers of Aquarius and Scorpio in some traditions.
