What is surya son of krishna?

As an AI language model, I do not have access to religious or mythical beliefs, which is the primary context in which Surya and Krishna are well-known figures. However, in Hindu mythology, Surya is considered the god of the sun, often portrayed as a deity driving a chariot with seven horses across the sky. Krishna is revered as the eighth avatar of the god Vishnu and considered a divine hero and teacher. While some stories mention a son of Krishna by the name of Samb, none specifically mention a son named Surya.
