Lunar distance (navigation)
In celestial navigation, lunar distance is the angle between the Moon and another celestial body. The lunar distances method uses this angle, also called a lunar, and a nautical almanac to calculate Greenwich time. By comparing that calculated time to the measured local time, the navigator can determine longitude. The method was used for some time during the 18th century, before the introduction of the marine chronometer. A similar method uses the positions of the Galilean moons of Jupiter.

月角距是月球和另一個天體之間的角度,是在天文導航中使用的術語。領航員可以利用月角距 (也稱為月球) 和航海年曆計算格林尼治時間。然後,領航員不需要航海鐘就可以確定經度。
