Recent analysis of telescopic data has proven that nearly six decades after its discovery, far-flung Pluto is indeed a planet and not an asteroid or satellite, researchers said. William McKinnon, associate professor of earth and planetary science at Washington University in St. Louis, said he has shown the composition of Pluto is just what is expected of a solid planet in the outer solar system. McKinnon said his research should put to rest the long-held notion that Pluto is a fugitive satellite that escaped Neptune's gravitational influence.
