ABU ABDULLAH AL-BATANI (858-929 A.D.)



Abu Abdullah Muhammad Ibn Jabir Ibn Sinan al-Batani al-Harrani was born around 858 A.D. in Harran. Batani was a famous astronomer, mathematician and astrologer. He has been held as one of the greatest astronomists of Islam. He is responsible for a number of important discoveries in Astronomy. His well known discovery is the remarkably accurate determination of the solar year as being 365 days, 5 hours, 46 minutes and 24 second, which is very close to the latest estimates.
Al Batani determined with remarkable accuracy the obliquity of the eclipse, the length of the seasons and the true and mean orbit of the sun.
He proved the variation of the apparent angular diameter of the sun and the possibility of annular eclipses. He rectified several orbits of the moon and the planets and propounded a new and very ingenious theory to determine the conditions of visibility of the new moon. His treatise on Astronomy was extremely influential in Europe till Renaissance, with translations available in several languages.
