Orbit
The periodic motion of a body around another under the pull of its gravity, distinct from Rotation, which is a body's spin about its own axis.
Pluto hasn't completed a full Orbit around the sun since its 1930 discovery. With an orbital period of about 248 years, it will finish its first lap in 2178. Counting from its 2006 demotion as a Solar System Planet, it will complete a full orbit in 2254.
