It was the year 2002 when this small planet was turned into a dwarf planet. Now our old planetary friend is called 134340. It was given the name by the Minor Planet Center. This isn’t the first planet that they renamed. They also renamed Charon, Nix, Hyrdra.

Even though Pluto is a dwarf planet, and no longer officially a planet, it’ll still be a fascinating target for study. And that’s why NASA has sent their New Horizons spacecraft off to visit it. New Horizons will reach Pluto in July 2015, and capture the first close-up images of the (dwarf) planet’s surface.
