Astronomical knowledge Since the early ages, human beings have been attracting attention. People are interested in the science of astronomy to build their lives in an orderly way and to maintain their daily lives. Naturally, this situation has set the stage for increasing interest in astronomy science from the ancient civilizations to the medieval civilizations. Basically, the Ancient and Medieval astronomy was developed by the influence of Ptolemy's Earth-centered (geocentric) astronomy. The geocentric universe model based on the studies of Ptolemy and mathematical theories maintained its existence as a correct thesis in astronomy until the time of Copernicus. However, there were some shortcomings in this theory. These shortcomings first raised objections from Egypt and then Andalusia. At this point, Nasîrüddîn Tysî and Merâga Mathematics-Astronomy School, which were active in the Mongolian period, developed an alternative planetary model. Especially the work of Nasîrüddîn Tûsî and Merâga Mathematics-Astronomy School has been an important step on the way to the present understanding of astronomy as proposed by Kopernik. In addition, Mongol astronomy has also contributed significantly to the development of Turkey's Seljuk astronomy. The fact that the scholars who are studying in Merâga Mathematics-Astronomy School have come to Anatolia, the transfer of some books in this school to Anatolia has prepared an atmosphere for Mongolian astronomy to affect Turkey's Seljuk astronomy.
