[漢羅] 月球 ê 東海 tī 月球 ê 西爿

月海 Mare Orientale tī 拉丁文內底是東海 ê 意思。 伊是月球面頂頭一个會注意著 ê 大型特徵。 若是 ùi 地球 ê 角度 來看，欲看著月球面頂上少年 ê 大型隕石坑盆地，實在是足困難 ê。 毋閣，若是利用月球 ê 天平動現象，to̍h 是等月球趨到某一个角度 ê 時陣，to̍h 會較好揣著東海。 東海 to̍h tī 這張清楚 ê 望遠鏡景色 ê 頂懸中央，伊 to̍h 勼 tī 月球西爿 ê 邊仔。 這个 隕石坑盆地 是 3 億年前去予小行星挵出來 ê，直徑差不多有 1000 公里闊。 隕石坑盆地內底有仝心圓特徵，月殼表面有水波痕。 遮攏是太空船欲翕月球 ê 時陣較好揣 ê 目標。 是講，是按怎月球 ê 東海是 tī 月球 ê 西爿邊仔 leh？ 這是因為月球上有名 ê 這个東海，是 1961 年進前號 ê 名。 彼當陣 leh 標 東爿 kah 西爿 ê 習慣 kah 這馬是顛倒反。

[English] Western Moon, Eastern Sea

The Mare Orientale, Latin for Eastern Sea, is one of the most striking large scale lunar features. The youngest of the large lunar impact basins it’s very difficult to see from an earthbound perspective. Still, taken during a period of favorable tilt, or libration of the lunar nearside, the Eastern Sea can be found near top center in this sharp telescopic view, extremely foreshortened along the Moon’s western edge. Formed by the impact of an asteroid over 3 billion years ago and nearly 1000 kilometers across, the impact basin’s concentric circular features, ripples in the lunar crust, are a little easier to spot in spacecraft images of the Moon, though. So why is the Eastern Sea at the Moon’s western edge? The Mare Orientale lunar feature was named before 1961. That’s when the convention labeling east and west on lunar maps was reversed.
