Mare Frigoris

Explanation: Lighter than typically dark, smooth, mare the Mare Frigoris lies in the far lunar north. Also known as the Sea of Cold, it stretches across the familiar lunar nearside in this close up of the waxing gibbous Moon’s north polar region. Dark-floored, 95 kilometer wide crater Plato is just left of the center. Sunlit peaks of the lunar Alps (Montes Alpes) are highlighted below and right of Plato, between the more southern Mare Imbrium (Sea of Rains) and Mare Frigoris. The prominent straight feature cutting through the mountains is the lunar Alpine Valley (Vallis Alpes). Joining the Mare Imbrium and Mare Frigoris, the lunar valley is about 160 kilometers long and up to 10 kilometers wide.

说明: 比一般黝黑平滑月海的颜色要淡一些的冷海,位在月面极北之处。在这幅盈凸月北极区的特写影像里,冷海绵延伸过熟悉的正面。在影像的中左侧,有95公里宽坑底黝黑的柏拉图坑。柏拉图坑的右下方,介于较南的雨海和冷海之间,可见到日曜的月表山脉(阿尔卑斯山)之群峰。而划过这个山脉的鲜明条形结构,则是阿尔卑斯月谷。这道连接雨海和冷海的月谷,长约160公里,最宽处有10公里。 (Mare Frigoris 冷海)
