So in the sun planet also, there are living entities, cities, just like here. Otherwise how Kṛṣṇa can say, imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1). Kṛṣṇa is telling lie, that "I spoke this science of Bhagavad-gītā to the sun-god?" Now, according to our calculation nobody can go to the sun planet, and where is the scope of speaking there, and to whom speaking? But Kṛṣṇa says, "Yes." Imaṁ vivasvate yogaṁ proktavān aham (BG 4.1), "I said," avyayam, "imperishable knowledge." Vivasvān manave prāha. So from this version we can understand, in the sun planet there are living entities, and the chief man, or chief demigod, is the sun-god, whose name is Vivasvān. So his body must be fiery; otherwise how he can live there? And the inhabitants there also.
