What is the Navagraha temple circuit in Tamil Nadu and which planet does each temple represent?

The nine temples and their planets

Each temple in the circuit is home to a presiding Shiva deity and also enshrines one of the nine grahas. The nine are:

Suryanar Kovil — the Sun (Surya) Thingalur — the Moon (Chandra) Vaitheeswaran Kovil — Mars (Angaraka) Thiruvenkadu — Mercury (Budha) Alangudi — Jupiter (Guru) Kanjanur — Venus (Shukra) Thirunallar — Saturn (Shani) Thirunageswaram — Rahu, the north lunar node Keezhperumpallam — Ketu, the south lunar node

All nine temples fall in the Kaveri delta region, mostly within a day's travel from Kumbakonam in the Thanjavur and Nagapattinam districts. This closeness is part of what makes the circuit practical as a pilgrimage.

Where this tradition comes from

The temples belong to the Agamic tradition of Tamil Shaivism and are very old. The Navagrahas, the nine planetary deities, have been part of temple worship in South India for a very long time. Each graha is understood not just as a planet but as a divine force that shapes a person's life according to their birth chart. The idea of grouping these nine temples into a single circuit grew from that belief, giving pilgrims a way to honour all nine grahas in one journey.

What the pilgrimage means

In Hindu astrology, each graha is believed to influence different parts of life, health, relationships, work, and fortune. When a planet sits in a difficult position in someone's chart, the tradition holds that visiting its temple, praying, and performing the right rituals can soften that influence. Saturn at Thirunallar is perhaps the most visited of all nine, as Saturn is seen as a powerful and testing force. Rahu at Thirunageswaram and Ketu at Keezhperumpallam draw many people too, since the lunar nodes are linked to eclipses and karmic patterns. The full circuit is seen as a way of bringing all nine planetary energies into balance.

Today

The circuit is active and well visited. Tamil families from around the world travel to Kumbakonam and make the round of all nine temples, often over one or two days. Some visit only the temple of the planet they feel is troubling them. Priests at each temple are familiar with the specific rituals tied to that graha. The pilgrimage is done for many reasons, from a difficult Saturn period to a child's first horoscope reading to a general wish for well-being. It remains one of the most recognisable pilgrimage traditions in Tamil Nadu.
