It is in a solar orbit 1.6 million kilometers from Earth.

它在距离地球160万公里的太阳轨道上。

How can the same sum total of solar orbits, lunar phases, terrestrial rotations, or transitions of a cesium-133 atom remain constant, but feel so different in our minds?

太阳轨道、月相、地球自转或铯 133 原子跃迁的总和怎么会保持不变，但在我们的脑海中却感觉如此不同？

Because of gravity, as Earth gets closer to the sun, it travels slightly faster in its solar orbit, which means there's more days on the June side of the equinoxes than on the December side and so on.

由于地心引力的影响，地球离太阳越近，它在太阳轨道上的运动速度越快，这意味着从春分到秋分之间的天数比从秋分到春分之间的天数长。

Because of gravity, as Earth gets closer to the sun, it travels slightly faster in its solar orbit, which means there's more days on the June side of the equinoxes than on the December side.

由于引力的作用， 当地球离太阳越来越近时，它在太阳轨道上的运行速度会稍微加快，这意味着春分点的六月一侧的天数比十二月一侧的天数多。
