Kepler’s Second Law, also known as the Law of Areas, states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. This means that a planet moves faster when it is closer to the Sun and slower when it is farther from the Sun.

Therefore, the slowest point of a planet’s orbit is always when it is:

b - Farthest from the Sun
