Kepler's 2nd Law, also known as the Law of Equal Areas, deals with 

• the elliptical shape of the planets' orbits and their distance from the sun

• the speed/area the planet travels in equal time intervals and its relation to the distance from the sun

• the length of time it takes the planet to orbit the sun and its relation to the planet's distance from the sun

• the gravitational pull between the planet and the sun

Considering Kepler's laws of planetary motion, how does the orbital period of a planet relate to its average distance from the sun? 

• The orbital period increases as the average distance from the sun increases

• The orbital period decreases as the average distance from the sun increases

• The orbital period is not affected by the average distance from the sun

• The orbital period is inversely proportional to the average distance from the sun
