It is classified as a rare class E asteroid and is probably the largest of this type (though 55 Pandora is only slightly smaller). == Discovery == It was discovered by Hermann Goldschmidt on May 27, 1857, and named after the mythical land of Nysa in Greek mythology. 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「44 Nysa」の詳細全文を読む スポンサード リンク
