Crash Course 天文篇

We call that line the ecliptic.

我们称这条线为黄道线。

亨利·亚当斯的教育（中）

The ecliptic had inclined itself beyond recovery till life was as thin as the elm trees.

黄道已经倾斜到无法恢复， 直到生命像榆树一样稀薄。

Crash Course 天文篇

From Earth, we see them sticking near the ecliptic, the line across the sky that marks the annual path of the Sun.

从地球上看，我们看到它们就贴在黄道附近，这条横跨天空的线标志着每年太阳的运行轨迹。

亨利·亚当斯的教育（下）

Nowhere had the new forces so vigorously corrected the errors of the old, or so effectively redressed the balance of the ecliptic.

新力量从未如此有力地纠正旧力量的错误，或者如此有效地纠正了黄道的平衡。

塔中恋人（上）

Her eyes were attracted by the brightness of the planet Jupiter, as he rode in the ecliptic opposite, beaming down upon her as if desirous of notice.

亨利·亚当斯的教育（中）

One of these errors was the inclination of the ecliptic; the other was the differentiation of the sexes, and the saddest thought about the last was that it should have been so modern.

黄道

黄道和赤道的关系：赤道是垂直地球自转轴的平面，与轨道平面（黄道）的夹角是轨道倾角，也就是黄赤交角。
从1994年克莱门特航天器拍摄的月球探测图片里能很好的观察到黄道平面。克莱门特拍摄的图片中（从右至左），月球被地球反射光照亮，太阳从月球较暗的一侧升起，然后依次是土星，火星和水星（左下角三个小点）。

黄道是在一年当中太阳在天球上的视路径，看起来它在群星之间移动的路径，明显的也是行星在每年中所经过的路径。更明确的说，它是球状的表面（天球）与黄道平面的交集；以几何学来描述，它是包含地球环绕太阳运行的平均轨道平面。

黄道不变平面（en:Invariable plane）是垂直所有行星轨道平面角动量和的平面，而木星应该是最主要的影响者。目前的黄道平面与不变黄道平面夹角约1.5°。

西方的黄道（ecliptic）一词是从蚀（eclipse）发生的地方延伸出来的。

由于地球公转受到月球和其他行星的摄动，地球公转轨道并不是严格的平面，即在空间产生不规则的连续变化，这种变化包括多项短周期的和一项缓慢的长期运动。短周期运动可以通过一定时期内的平均加以消除，消除了周期运动的轨道平面称为瞬时平均轨道平面。黄道的严格定义是：地月系质心绕太阳公转的瞬时平均轨道平面与天球相交的大圆。黄道是天球上黄道坐标系的基圈。

Ecliptic 黄道

The Sun seems to move against the background stars as seen from the orbiting Earth. The ecliptic is the path the Sun appears to trace through the stars. This process repeats every time in a little over 365 days.
The plane of Earth's orbit projected in all directions forms the reference plane known as the ecliptic. Here, it is shown projected outward (gray) to the celestial sphere, along with Earth's equator and polar axis (green). The plane of the ecliptic intersects the celestial sphere along a great circle (black), the same circle on which the Sun seems to move as Earth orbits it. The intersections of the ecliptic and the equator on the celestial sphere are the vernal and autumnal equinoxes (red), where the Sun seems to cross the celestial equator.
Obliquity of the ecliptic for 20,000 years, from Laskar (1986).[12] Note that the obliquity varies only from 24.2° to 22.5° during this time. The red point represents the year 2000.

The ecliptic is the apparent path of the Sun on the celestial sphere, and is the basis for the ecliptic coordinate system. It also refers to the plane of this path, which is coplanar with the orbit of Earth around the Sun (and hence the apparent orbit of the Sun around Earth). The path of the Sun is not normally noticeable from Earth's surface because Earth rotates, carrying the observer through the cycles of sunrise and sunset, obscuring the apparent motion of the Sun with respect to the stars.
