Unlike many of the planets in the solar system, such as Earth, Pluto does not bulge at its center; its radius â 1,185 km (737 miles) â is the same at its poles and at its equator. Circumference: If you were to take a walk around the equator of Pluto, you would travel about 4,627 miles (7,445 km). That is just a bit less than the distance from Denver to London (4,683 miles). Pluto is thought to have a rocky core covered by ice, which would mean that its surface features would change with temperature as it travels closer to and farther from the sun.
