Interesting Facts about Pluto

Pluto is the second largest dwarf planet of the Solar System. Until very recently it was actually considered to be the ninth planet in the solar system and the furthest from the sun. It is one of several large bodies in a newly discovered region known as the Kuiper Belt. Pluto is made up of mostly ice and rock and is smaller in mass and volume than the Moon. Pluto does not orbit the sun on the same plane that the other planets do, but has a higher more elongated orbit.
