It might not be widely known that under the ‘Abbasid Muslim rulers, Arabs and Persians made many advances in astronomy, naming many stars, as well as copying and correcting some of Ptolemy’s tables. However, the sun is many times larger than the entire earth, and the earth travels around the sun.
Inawezekana kuwa haijulikani kwa mapana kwamba watawala wa kislam wa Abbasid, Waarabu na Waajemi waliendelea sana katika unajimu, wakizipa majina nyota nyingi, hata walinukuru na kusahihisha baadhi ya orodha za hesabu za watawala wa Misri (Ptolemy’s tables). Hata hivyo jua ni kubwa mara nyingi zaidi ya dunia nzima, na dunia husafiri ikilizunguka jua.
