Greaves is a small lunar impact crater that lies near the southwest edge of Mare Crisium. It is a circular, bowl-shaped formation with a small interior floor at the center of the sloping inner walls. The crater is intruding into the northern edge of the lava-flooded crater Lick. To the northwest is Yerkes, and to the northeast is Picard. This formation was previously designated Lick D, a satellite crater of Lick, before it was given a name by the IAU. ==References== * * * * * * * * * * * * 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「Greaves (crater)」の詳細全文を読む スポンサード リンク
