Surya Siddhanta
पश्चाद् व्रजन्तो +अतिजवान् नक्षत्रैः सततम् ग्रहाः। जीयमानास् तु लम्बन्ते तुल्यम् एव स्वमार्गगाः ॥
Now the planets (such as the Sun) being on their orbits, go very rapidly and continually with the stars towards the west and hang down (from their places towards east) at an equal distance, (i. e. they describe equal spaces daily towards the east,)[1] as if overpowered by the stars (by reason of their very rapid motion caused by the air called Pravaha.)
english translation
pazcAd vrajanto +atijavAn nakSatraiH satatam grahAH। jIyamAnAs tu lambante tulyam eva svamArgagAH ॥
