Pluto is considered a dwarf planet, and it is about 3.7 billion miles from the sun. Until it was reclassified in 2006, Pluto was the ninth and furthest planet from the sun.
Pluto is located in the Kuiper Belt, which is home to more than a trillion other comets. At the time of its discovery in 1930, Pluto was the first and only planet named by an 11-year-old girl in England. Made mostly of ice and rock, this dwarf planet is about one-sixth the size of Earth's moon, and it has six of its own moons that orbit this distance planet.
