ecliptic

On the astrolabe, an off - centered circle represents the orbit of the sun - the ecliptic.

在星盘上， 一个偏心的圆代表了太阳的运行轨道――黄道。

Recall that vernal equinox is one of the two intersection points of the celestial equator and the ecliptic.

赤经计算的起点为春分点，相信你仍记得春分点是天球赤道和黄道的其中一个相交点。

Because the Moon and bright planets wander through the sky near the ecliptic plane, such occultation events are not uncommon, but they are dramatic, especially in telescopic views.

因为月球和明亮的行星出现在天空中黄道平面附近，这种掩星事件也很平常，但是它们也很富有戏剧性，特别是在望远镜影像里。
