Some people think that it is too small and is not even the force that acts upon the orbit of Neptune. It is even thought that Triton, Neptunes moon might have been like Pluto, but then got caught in Neptunes gravitational pull. (space.com) Pluto was discovered in 1930 by a fortunate accident. Calculations, which later turned out to be in error, had predicted a planet beyond Neptune, based on the motions of Uranus and Neptune. A spacecraft has not yet visited Pluto. Even the Hubble Space Telescope can resolve only the largest features on its surface (left and above). A spacecraft called New Horizons was launched in January 2006.
