Trans-Neptunian objects are out there in the darkness and distance of space known more commonly among astronomers as "the third zone" in the solar system. Beyond the orbit of Neptune and towards the Kuiper belt there are thousands of big objects, almost like another asteroid belt but larger ones that they could be called dwarf planet. Even planet Pluto is now considered to be one of these objects, as unfortunately its not recognised as a planet, [10minVid]. NASA's New Horizons spacecraft is in route to Pluto for July 2015 encounter and on into "the third zone" thereafter. Sunday, August 22, 2010
