Surya is the chief of the Navagraha, the nine Classical planets and important elements of Hindu astrology. He is often depicted riding a chariot harnessed by seven horses which might represent the seven colors of the rainbow or the seven chakras in the body. He is also the presiding deity of Sunday.

Surya is regarded as the Supreme Deity by Saura sect and Smartas worship him as one of the five primary forms of God. The Sun god, Zun, worshipped by the Afghan Zunbil dynasty, is thought to be synonymous with Surya.
