The eight planets of our solar system orbit in the same direction along what's called the ecliptic, a flat plane that's nearly aligned with the sun's equator.
太阳系中的八大行星都沿着同一方向在被叫作黄道面(这一平面与太阳赤道面形成微小的夹角)运行。

If we plot the position of the sun around the sky in a year, it will mark out a different circle in the sky which is the plane of the ecliptic of the solar system.
如果我们将太阳在天空中的一年内运转轨迹描出，这将是另一个循环，这平面就是整个太阳系的黄道。
