Text

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 koá¹­i means ten million, and a yojana is eight miles. The diameter of the universe is fifty koá¹­i 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 koá¹­i yojanas (two billion miles).
