And on the day of the equinox, the plane of Earth's equator is intersecting the ecliptic - or plane of Earth's orbit around the sun. So the sun sets due west for all of us.
在秋分这一天，地球上赤道正是黄道相交——或者是地球平面轨道环绕太阳，造成我们看到太阳在正西方落下的现象。
And on the day of the equinox, the plane of Earth's equator is intersecting the ecliptic – or plane of Earth's orbit around the sun.
