TRANSLATION
The sun is situated [vertically] in the middle of the universe, in the area between Bhūrloka and Bhuvarloka, which is called  antarikṣa , outer space. The distance between the sun and the circumference of the universe is twenty-five  koṭi yojanas  [two billion miles].
PURPORT
The word  koṭi  means ten million, and a  yojana  is eight miles. The diameter of the universe is fifty  koṭi yojanas  (four billion miles). Therefore, since the sun is in the middle of the universe, the distance between the sun and the edge of the universe is calculated to be twenty-five  koṭi yojanas  (two billion miles).
