Kepler’s Second Law explains that the slowest point of a planet’s orbit is always when it is

Question

a Closest to the Sun
b Farthest from the Sun
c In the mid point of the orbit
d As it approaches either of the foci

Answer 1

Kepler’s Second Law, also known as the Law of Equal 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 occurs when it is:

b Farthest from the Sun.
