E)planets have circular orbits.

Kepler's second law implies that a planet moves faster when it is closer to the Sun and slower when it is further away from the Sun. This is because, as the planet approaches the Sun, it experiences a stronger gravitational force, which causes it to accelerate. As the planet moves away from the Sun, the gravitational force becomes weaker, and the planet slows down.
