Astronomy:- علم الهيئة أحد الأقسام الاصلية للحكمة الرياضية «يعرف فيه حال اجزاء العامل في اشكالها، واوضاع بعضها عند بعض ومقاديرها، وابعاد ما بينها، وحال الحركات التي للافلاك، والتي للكواكب، وتقدير الكرات، والقطوع، والدوائر التي بها تتم الحركات، ويشتمل عليها كتاب المجسطي» (رسالة ابن سينا في اقسام العلوم العقلية، تسع رسائل في الحكمة والطبيعيات، الرسالة الخامسة، ص 111 - 112).
