ecliptic

ecliptic的音标是["i:klɪpɪt] 。基本翻译是黄道。速记技巧是利用词根记忆，ec-表示向外，-litic表示…的，所以ec-litic就是表示向外的部分。

Ecliptic这个词源于希腊语中的“eklektos”，意为“平行的”。它的变化形式包括其复数形式“eclipts”和过去式、过去分词形式“eclipted”。

The Ecliptic: An Important Reference for Astronomy

The ecliptic is an imaginary line that passes through the sun and the Earth, and it plays a crucial role in astronomy. Objects in the sky appear to move along the ecliptic, and this motion can be used to determine their positions and movements. The ecliptic also helps us understand how the solar system and other celestial bodies interact with each other. Understanding the ecliptic allows us to make more accurate predictions about celestial events, such as solar eclipses and lunar phases. In addition, studying the ecliptic can help us better understand our own planet, as it provides information about its orientation and motion in space. Therefore, the ecliptic is an essential reference for astronomers and other scientists studying the universe.
