However, its motion around the Sun is faster at perihelion than aphelion.
然而,它在近日点比在远日点时公转更快。
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.
