Early Period:
* Muhammad ibn Musa al-Khwarizmi (c. 780-850): Not primarily known for planetary studies, but his work on algebra and trigonometry provided foundational tools for astronomical calculations.
* Muhammad ibn Jābir ibn Sinān al-Battānī (c. 858-929): Developed more accurate planetary models than his predecessors and produced a comprehensive star catalog.
Golden Age of Islamic Astronomy:
* Al-Battānī (above): His work influenced later European astronomers like Copernicus.
* Abū Rayhān al-Bīrūnī (c. 973-1048): He conducted precise observations of planetary positions and developed innovative methods for calculating planetary motion.
* Ibn Yunus (c. 950-1009): Known for his exceptionally accurate observations of the sun and moon, which he used to refine astronomical tables.
* Al-Zarqālī (c. 1029-1087): Developed astronomical tables that improved upon earlier models and were used for centuries.
* Nasir al-Din al-Tusi (1201-1274): Developed a model of planetary motion that challenged the Ptolemaic system and paved the way for Copernicus' heliocentric theory.
Later Period:
* Ulugh Beg (1394-1449): A Timurid prince who built an observatory and created a highly accurate star catalog.
* Ali Qushji (1403-1474): A prominent supporter of the heliocentric model of the solar system and wrote extensively on planetary motion.
It's important to note that these individuals and their contributions are just a small sampling of the vast and diverse history of Muslim astronomy. Their work built upon earlier Greek traditions and ultimately influenced the development of modern astronomy in Europe.
Instead of focusing on a singular "movement," it's more accurate to recognize the continuous and ongoing contributions of Muslim scholars over several centuries to our understanding of the planets.
