Write a blog post about the planet Pluto, add some general facts about it and keep the word count under 200. 
Pluto is a dwarf planet, but it wasn't always considered a "dwarf" planet and for quite some time was considered the ninth planet in the solar system. Before going into those details, let's discuss what Pluto is. Pluto is a dwarf planet within the Kulper Belt, this belt represents a ring of bodies that are outside the orbit of Neptune. Pluto is very far from the Sun, but despite that, it still orbits it and is considered the ninth-largest object to orbit the Sun. This distance however means that Pluto is made mostly of ice and rock. Despite Pluto's small size, it has five moons, the largest being Charon. 

Pluto was originally discovered back in 1930 and was the first object in the Kulper belt. As soon as it was discovered, it was hailed as the ninth planet. It's important to note that since its discovery, Pluto's planetary status was questioned as soon as it was discovered that its size was much smaller than expected. In the year 2006, the International Astronomical Union (IAU) redefined the word planet to exclude dwarf planets such as Pluto.
