Navagraha — 9 Planets

The nine grahas (Navagraha) in Vedic astrology are: Sun (Surya), Moon (Chandra), Mars (Mangala), Mercury (Budha), Jupiter (Brihaspati), Venus (Shukra), Saturn (Shani), Rahu, and Ketu. The first seven are the visible celestial bodies recognised across ancient astronomy; Rahu and Ketu are the lunar nodes — the two mathematical points where the Moon's orbit intersects the ecliptic. Together these nine grahas form the foundation of Jyotish chart interpretation and dasha timing.

Rahu and Ketu are called shadow planets (Chhaya Graha) because they are not physical bodies — they are the north and south lunar nodes, calculated as the intersection points of the Moon's orbital path and the Sun's apparent path (the ecliptic). Vedic tradition describes them as the severed head and tail of the serpent Svarbhanu, responsible for eclipses when the Sun or Moon passes through these points. Because they have no physical form but produce powerful effects in a birth chart, classical Jyotish texts classify them separately as shadow or node grahas.

In Vedic astrology, benefic grahas (Shubha Graha) naturally support growth, harmony, and positive outcomes, while malefic grahas (Krura or Papi Graha) tend to produce friction, obstacles, or intensity that requires effort to navigate. Natural benefics among the Navagraha are Jupiter (Brihaspati), Venus (Shukra), and the waxing Moon (Chandra); natural malefics are Sun (Surya), Mars (Mangala), Saturn (Shani), Rahu, and Ketu. Traditional Jyotish also recognises functional benefics and malefics, which depend on a planet's sign lordship relative to the individual's Lagna (ascendant) — so no graha is universally good or bad in all charts.

Each graha influences the life domains governed by the house it occupies and the houses it aspects in the birth chart (kundali). For example, Jupiter placed in the 5th house is associated with children, creativity, and education, while Saturn in the 10th house tests career and public reputation. Classical texts like Brihat Parashara Hora Shastra describe specific results for each graha in each house position, modified further by the graha's strength (shadbala), sign placement (rashi), and relationships with other grahas. The chart shows tendencies and predispositions, not fixed outcomes.

Graha yuddha, meaning planetary war, occurs in Vedic astrology when two grahas come within one degree of each other in the same sign of the zodiac. The planet with the higher ecliptic latitude is generally considered the winner of the war. Traditional Jyotish holds that the losing planet's significations become weakened or suppressed during the period that war is active. Only the five true planets (Mars, Mercury, Jupiter, Venus, Saturn) can participate in graha yuddha — the Sun, Moon, Rahu, and Ketu are excluded from this classification.

Traditional Jyotish assigns one primary gemstone to each of the nine grahas: Ruby (Sun), Pearl (Moon), Red Coral (Mars), Emerald (Mercury), Yellow Sapphire (Jupiter), Diamond (Venus), Blue Sapphire (Saturn), Hessonite or Gomed (Rahu), and Cat's Eye or Lehsunia (Ketu). Gemstones are worn as upay (remedies) to strengthen a graha's positive influence in the chart. Traditional practice recommends consulting an experienced Jyotishi before wearing a planetary gemstone, as strengthening a malefic planet in certain chart positions can amplify its challenges rather than resolve them.

Classical Jyotish (Vedic astrology) works exclusively with the nine Navagraha and does not use Uranus, Neptune, or Pluto. These outer planets were unknown to the ancient Parashara and Varahamihira traditions, and the entire predictive system — dasha periods, house rulerships, aspect rules — is built around the nine grahas only. Some modern Vedic astrologers have begun incorporating the outer planets as supplementary indicators, but this is not traditional practice and is not universally accepted among classical Jyotishis. For traditional chart readings, the nine Navagraha remain the complete and self-sufficient framework.

Traditional Navagraha puja involves offering specific materials associated with each graha — for example, red flowers and wheat for Surya (Sun), white rice and milk for Chandra (Moon), and sesame seeds and black cloth for Shani (Saturn). The Navagraha Stotra and individual planet mantras (such as the 108-name Surya Ashtottara) are recited to propitiate each graha. Japam — the repetitive chanting of a graha's beej (seed) mantra — is a common daily practice; Surya's beej mantra is Om Hram Hrim Hraum Sah Suryaya Namah, and each planet has an equivalent. Major temples dedicated to the Navagraha, most famously the nine-temple cluster near Kumbakonam in Tamil Nadu, attract pilgrims seeking planetary blessings through abhisheka (ritual bathing of the deity) and archana (flower offering).
