However, its motion around the Sun is faster at perihelion than aphelion.
然而,它近

点时公转更快。
The corresponding change in gravitational force causes the Earth to move fastest in January when it reaches its closest point to the Sun, the perihelion, and the slowest in July when it reaches its farthest point, the aphelion.
相应的地球引力的变化使地球一

到达离太阳最近的点时,这个点被称作“近
点”,到达离太阳最
的点时,公转最慢,这个点也被称作“
