"Sanjaya said,--'Indeed, O great king, the islands have all been described to thee. Listen now to what I truly say about the heavenly bodies and about Swarbhanu, O chief of the Kauravas, as regards its dimensions. It is heard, O king, that the planet Swarbhanu is globular. Its diameter is twelve thousand Yojanas, and its circumference, because it is very large, is forty-two thousand Yojanas, O sinless one, as said by the learned of olden times. The diameter of the moon, O king, is stated to be eleven thousand Yojanas. Its circumference, O chief of the Kurus, is stated to be thirty-eight thousand nine hundred Yojanas of the illustrious planet of cool rays. It hath been heard that the diameter of the beneficent, fast going and light-giving Sun, O thou of Kuru's race, is ten thousand Yojanas, and his circumference, O king, is thirty-five thousand eight hundred miles, in consequence of his largeness, O sinless one. These are the dimensions reckoned here, O Bharata, of Arka. The planet Rahu, in consequence of his greater bulk, envelops both the Sun and the Moon in due times. I tell thee this in brief. With the eye of science, O great king, I have now told thee all that thou hadst asked. Let peace be thine. I have now told thee about the construction of the universe as indicated in the Shastras. Therefore, O Kauravya, pacify thy son Duryodhana. '
