Srimad-Bhagavatam: Canto 5 - Chapter 1 - Verse 10

Sanskrit:

यदा चैन्द्य्रा: पुर्या: प्रचलते पञ्चदशघटिकाभिर्याम्यां सपादकोटिद्वयं योजनानां सार्धद्वादशलक्षाणि साधिकानि चोपयाति ॥ १० ॥

ITRANS:

yadā caindryāḥ puryāḥ pracalate pañcadaśa-ghaṭikābhir yāmyāṁ sapāda-koṭi-dvayaṁ yojanānāṁ sārdha-dvādaśa-lakṣāṇi sādhikāni copayāti.

Translation:

When the sun travels from Devadhānī, the residence of Indra, to Saṁyamanī, the residence of Yamarāja, it travels 23,775,000 yojanas [190,200,000 miles] in fifteen ghaṭikās [six hours].

Purport:

The distance indicated by the word sādhikāni is pañca-viṁśati-sahasrādhikāni, or 25,000 yojanas. That plus two and a half crores and twelve and a half lakṣa of yojanas is the distance the sun travels between each two cities. This comes to 23,775,000 yojanas, or 190,200,000 miles. The total orbit of the sun is four times that distance, or 95,100,000 yojanas (760,800,000 miles).
