220 Stephania is a Main belt asteroid. It is a P-type asteroid, meaning it is relatively dark and composed of organic rich silicates, carbon and anhydrous silicates. It was discovered by Johann Palisa on May 19, 1881 in Vienna. It was the first discovery he made after transferring to the observatory from Pola.〔Schmadel Lutz D. ''Dictionary of Minor Planet Names'' (fifth edition), Springer, 2003. ISBN 3-540-00238-3.〕 The name honours Crown Princess Stéphanie, wife of the heir-apparent Crown Prince Rudolf of Austria. The couple was married the year the asteroid was discovered. It was the first time that a naming commemorated a wedding and was given as a wedding gift.〔 Lightcurve data has also been recorded by observers at the Antelope Hill Observatory, which has been designated as an official observatory by the Minor Planet Center.〔(Lightcurve Results )〕 == References == *(The Asteroid Orbital Elements Database ) *(Minor Planet Discovery Circumstances ) *(Asteroid Lightcurve Data File ) 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「220 Stephania」の詳細全文を読む スポンサード リンク
