Surya (Sun) is the most important planet as well as a deity. Worshiping Surya increases prana-shakti (life-force), it rays destroy many diseases and it is the biggest source of never ending energy. There is a Strota, called Surya-Kavach, it is chanted for protection, as a deity his protection is very strong — remember the case of Karna in Mahabharata, he was invincible due to Surya-Kavach. This Surya-Kavach wasn’t as it is shown in movies, it was a Mantrik protection which Karna had and on Indra request he promised not to use it in the war. We take note of popular deities, but Surya as a deity is not lesser than others — though there are less Sanskrit literature on Surya (as I know), but whatever it is, like Surya Kavach and Aditya Hriday Strota, I think, is very potent.
