Q:

Does Pluto follow Kepler’s Second Law?

A:

Yes! All objects in orbit follow Kepler's Second Law, and all of Kepler's other laws too. Like any other object in our solar system, Pluto moves faster when its closer to the sun and slower when its farther away.

 

Pluto is special because its orbit doesn't follow the plane the planets are in. But that's ok! The law works in three dimensions, not just two, because space extends in every direction.
