Li Fan (Chinese:李梵, around 90) was a Chinese astronomer during the Han Dynasty (202 BC-220 AD). He noticed that the Moon does not move uniformly through its phases by using background stars as reference. A crater on Mars was named in his honor. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Li Fan (Han dynasty)」の詳細全文を読む スポンサード リンク
