What Is Pluto's Period of Revolution?

At a distance of 3.67 billion miles from the sun, Pluto has a period of revolution that takes 247.8 years to complete, according to About.com. One day on Pluto is equivalent to 6.39 Earth days.

Its unusual orbit has Pluto coming inside of Neptune's orbital path at times. Classified as a dwarf planet as of 2006 by the International Astronomical Union, Pluto has three known satellites: Charon, Hydra and Nix. Even so, Pluto itself is smaller in size than the Earth's moon and six other moons in the solar system. Charon revolves around Pluto every 6.39 days and also rotates once during that span of time, making it identical to the rotation period of Pluto.
