New Horizons is a NASA spacecraft mission currently moving toward Pluto. It is expected to be the firsts pacecraft to fly by and study this dwarf planet and its moons, Charon, Nix, and Hydra.
New Horizons was launched on January, 2006. It flew by Jupiter on February, 2007, and orbited Saturn on June, 2008. It will arrive at Pluto on July, 2015, after which it will continue into the Kuiper belt.
Pluto is the largest object of the Kuiper belt, which is the region of the Solar System extending from the orbit of Neptune (at 30 AU) to approximately 55 AU from the Sun. The belt consists mainly of small bodies, remnants from the Solar System's formation. It is the home to at least three dwarf planets – Pluto, Haumea, and Makemake. Some of the Solar System's moons, such as Neptune's Triton and Saturn's Phoebe, are also believed to have originated in the region.
