Hill is a small lunar impact crater that is located to the west of the prominent crater Macrobius, near the eastern edge of the Sinus Amoris. This crater was previously designated Macrobius B before being given a name by the IAU. It lies just to the north-northeast of Carmichael, another renamed satellite crater of Macrobius. This is a circular, bowl-shaped crater with an inner wall that has a relatively high albedo compared to the surrounding terrain. The inner walls are symmetrical in form, and slope gently down to the small floor at the midpoint, a surface about one-fourth the diameter of the crater. This formation is not significantly eroded, and is otherwise indistinguishable from many similar craters on the Moon. ==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「Hill (crater)」の詳細全文を読む スポンサード リンク
