Seven Horses names of Surya

Surya is the chief of the Navagraha, Indian "Classical planets" and important elements of Hindu astrology. He is often depicted riding a chariot harnessed by seven horses or one horse with seven heads, which represent the seven colours of the rainbow or the seven chakras. He also presides over Sunday. Surya is regarded as the Supreme Deity by Saura sect, which is now a very small following. Smartas worship him as the five primary forms of God.
Surya as the Sun is worshipped at dawn by most Hindus and has many temples dedicated to him across India. He also enjoys worship as a part of the Navagraha. He is especially worshipped in the Hindu festivals of Ratha Saptami, Makar Sankranti, Chhath and Samba Dashami.

Surya rides across the sky in a golden chariot drawn by seven white horses, personifications of the days of the week.
